In this article, we will explore the power of code in graphic design and how it can revolutionize the industry.
When it comes to testing code on the Arduino, every second counts. Copying and pasting code into the Arduino editor can be time-consuming, especially when you need to make frequent modifications. In this article, we will explore a method to drastically reduce the time required for testing code on the Arduino, allowing developers to focus on UI design and functionality.
Creating Images and Icons
When starting a project that requires images and icons, the usual process for me would involve using software like Photoshop or a free online editor called PhotoP. I would use tools such as the pencil tool to draw rectangles, outlines, add labels, and create lines. By filling in individual pixels, I could achieve the desired look for my images and icons.
Exporting Images for Arduino
Once I am satisfied with the design, the next step is to transfer these images onto an OLED screen. However, this requires additional steps. Firstly, I need to export each individual icon as an image. To convert these images into C style arrays suitable for Arduino, I use websites like Image to CPP. After obtaining the arrays, I can easily copy and incorporate them into my Arduino sketch.
Using the Draw xbmp Function
With the arrays in place, I can then utilize the draw xbmp function in my Arduino sketch to display these images on the OLED screen. However, this function requires the positioning of the icons. Hence, I have to refer back to PhotoP to determine the precise position of each icon. Although this process only takes a few clicks, it needs to be repeated for every single icon.
Labels and Other Elements
Aside from icons, there are other elements to consider as well. For instance, if I want a progress bar to be drawn as a rectangle, I have to go back to PhotoP and find the coordinates for the correct position. This manual process can be time-consuming and tedious, especially when dealing with multiple labels and elements.
Overall, this traditional approach of creating images and icons for Arduino projects can be quite labor-intensive. The frequent switch between software and repetitive tasks can slow down the development process. However, there may be a solution to streamline these steps and make the entire process more efficient. Stay tuned to find out more about PCB Way and how they can simplify the creation of images and icons for Arduino projects.

Exploring the Power of Code in Graphic Design
Unveiling the Code Tab
When diving into the code aspect of graphic design, a whole new world opens up. By switching tabs, designers are introduced to a line of code that specifies the parameters of their artwork. For instance, a simple command such as “draw frame” with designated X and Y positions, as well as the width and height, can create a visually appealing frame. The beauty is that any changes made to these values in the interface are reflected in the code, ensuring a seamless connection between the design and its underlying code structure. This feature not only allows for experimentation but also facilitates efficient workflow.
Expanding the Creative Horizon
With code at their disposal, designers can unlock a multitude of possibilities. Frames, which are outline rectangles, become just the tip of the iceberg. By leveraging code, boxes, lines, dots (individual pixels), circles (both outline and filled), and even labels can be effortlessly created. This newfound flexibility grants designers the freedom to explore unconventional shapes and arrangements that might have been challenging to achieve using traditional graphic design tools alone.
The Power of Customization
One of the most remarkable features of working with code in graphic design is the ability to customize every aspect of an element. The selection tool offers a convenient method to modify any object by simply clicking on it in the interface. This grants access to a panel where parameters such as size, position, and appearance can be fine-tuned to achieve the desired effect. Furthermore, predefined icons can be effortlessly added by selecting them from a dedicated tab and dragging them onto the canvas, enabling designers to enhance their creations with ready-made visual elements.
By embracing the power of code in graphic design, designers can streamline their workflow and significantly reduce time-consuming tasks. Gone are the days of remembering complex numerical values for each design element. With the code readily available, designers can simply reuse snippets of code from previous projects or utilise libraries and frameworks to expedite the development process. This newfound efficiency not only allows for faster turnarounds but also opens up opportunities for innovation and exploration.
Creating Custom Images

With the ability to import your own image or draw from scratch, the possibilities are endless. By simply clicking on the desired element and drawing the individual pixels, you have full control over the appearance. Use the left mouse button to fill in pixels and the right mouse button to delete them. You can even delete entire elements by clicking on the “x” icon next to them. Alternatively, if you want a clean slate, clicking the reset button will clear everything.
Building a Progress Bar Screen
To demonstrate the process, let’s create a progress bar screen. Start by drawing the frame around the desired size, ensuring it is proportionate and visually pleasing. Next, draw a box to represent the fill of the progress bar. Adjust its position to align it with the frame and leave a small pixel gap on one side. To add meaningful content, change the string on the screen to something relevant, like “Progress” followed by a value, such as 60 percent.
Add Text and Typography
To enhance the visual appeal of the progress bar screen, consider adding a screen title. Insert a new string on the top of the screen and choose an appropriate font. Experiment with different fonts until you find one that matches the overall style and feel of your design. Once you have selected the perfect font, align it to the left side for better readability.
Create a Visual Divider
To separate the top of the screen from the middle section, draw a new line. This line will act as a visual divider, adding structure and improving the overall user experience. By clearly marking different sections of the screen, users can easily navigate and understand the layout.
Creating custom images and designing interfaces can be a fun and creative process. With the option to import images or draw from scratch, you have complete control over the appearance of different elements. By following a structured approach and paying attention to details such as typography and visual dividers, you can create visually appealing and user-friendly designs. So, let your creativity flow and start experimenting with different design elements today.
Enhancing the User Interface with Icons
Icons have become an integral part of user interfaces, offering a visually appealing way to convey information or perform specific actions. In this article, we will explore how to add icons to your interface to enhance its functionality and aesthetics.
Moving Icons Around
The positioning of icons plays a crucial role in determining the overall layout of your interface. By strategically moving icons, you can create a more balanced and visually pleasing design. Let’s take a look at some examples.
One popular icon is the lock icon. Traditionally, it is placed on the left side of the interface, but why not experiment? Try moving it to the right side and see how it influences the overall look. Similarly, you can add other icons such as the Bluetooth and volume icons to the right side as well. This arrangement adds a sense of symmetry and tidiness to your interface.
You can also have some fun and rearrange the existing icons. Select the ones you want to move and drag them to different positions. This flexibility allows you to customize the interface according to your preferences.
Adding the Warning Icon
While it’s great to have a variety of icons, sometimes you need to add a new one to convey a specific message or alert the user. Let’s say you want to include a warning icon. Simply locate the desired position, perhaps next to a label, and place the icon there. You can fine-tune its placement by using the arrow keys for precise adjustments.
Don’t forget about the label itself. If you feel that it needs to be moved to the right side to create a better visual composition, go ahead and make that adjustment. This level of control allows you to achieve a harmonious balance within your interface.
Testing on an Arduino Emulator
Now that you’ve made all the necessary adjustments, it’s time to see how your interface looks and functions in action. One way to do this is by using an Arduino emulator. Walkway, a free online Arduino emulator, provides a convenient platform for testing your interface.
Open the emulator and load your previous project, such as the “Image to OLED in 60 seconds” sketch. Connect your Arduino Uno to the OLED screen, and when you run the simulation, you will see the interface with all the icons and their updated positions.
Take a moment to appreciate the transformation you have made. The added icons, rearranged positions, and overall improved user interface create a more engaging and user-friendly experience.
Adding icons to your interface can significantly enhance its visual appeal and functionality. By experimenting with different positions and incorporating new icons when needed, you can create a unique and captivating user experience. So why not get started and bring your interface to the next level with icons?
The Initialization of the Library
In order to display anything on the Arduino Uno, we first need to initialize the library of the display. This can be done by including the necessary header file and calling the appropriate functions.
Setting Up the Display
Once the library is initialized, we can proceed with setting up the display. This involves calling the “begin” function, which prepares the display for use. This function typically takes parameters such as the display address and the display resolution.
Main Loop and Drawing to the Display
In the main loop of our Arduino program, we have the code to clear the display buffer. This ensures that any previously displayed content is removed before we proceed with drawing new content.
After clearing the buffer, we can then send the buffer to the display. This will result in the drawing of whatever is stored in the buffer onto the display. This allows us to create various shapes, lines, and images on the display.
Using the Lopaka Editor
To make the process easier, we can use the Lopaka editor to generate the code for our design. By copying the code from the Lopaka editor and pasting it into our program, we can quickly implement complex designs without writing all the code manually.
Additionally, we may need to move the image arrays outside of the loop to ensure that they are accessible throughout the program. This is a simple adjustment that needs to be made for proper execution.
Visualizing the Design
By restarting the simulation or running the program on a real Arduino Uno, we can witness the design we created on the display. Whether using the emulator or the physical Arduino, the display should showcase the same design as seen in the Lopaka editor. This allows for quick and accurate visualization of the desired output.
Size Doesn’t Matter: Exploring Different Versions of Arduino Displays
Arduino displays are versatile tools that can greatly enhance your projects. Whether you’re a beginner or an experienced Arduino enthusiast, there are various sizes of displays available to suit your needs. In this article, we will explore three different versions of Arduino displays, each with its own unique advantages and applications.
Choosing the Right Size
The physical size of an Arduino display can make a significant difference in your project. The three versions we will discuss range from the smallest 0.9 inch size, to the middle-sized 1.5 inch, and the largest 2.4 inches. Don’t be fooled by their small sizes, as these displays pack a powerful punch when it comes to displaying information and graphics.
Connecting the Display
In order to connect the display to the Arduino, you will need some jumper wires. The connection process is straightforward and follows the same pattern as outlined on the official Arduino website. The ground wire goes to the ground pin, while the VCC wire connects to the 5 volts pin. The scl, or serial clock, wire goes to pin A5, and the SDA, or serial data, wire goes to pin A4. If you find it difficult to remember these pins, don’t worry! Most Arduino boards have dedicated SDA and SCL pins that are properly labeled.
Using the u8 G2 Library
In order to utilize the full potential of your Arduino display, you need to use the u8 G2 library. If you have never used this library before, you will need to install it first. Simply go to the libraries section on your Arduino IDE, type in “u8 G2,” and click the install button. If you already have this library installed, you may see an update button instead.
Uploading the Code
Once you have everything connected and the u8 G2 library installed, you can now upload the code to your Arduino board. Select the correct board from the Arduino IDE, and click the upload button. After a few seconds, you should see the same sketch running on your real Arduino board.
Making It More Exciting
By default, the sketch on your Arduino board might appear static and dull. However, you can easily fix this by utilizing the u8 G2 functions to add movement and animation. Instead of relying on full-screen images, these functions allow you to draw and manipulate various elements on your display, bringing your projects to life.
With the u8 G2 library and different sizes of Arduino displays at your disposal, the possibilities are endless. Whether you want to create a simple interactive project or a complex graphical representation, these displays offer a world of opportunities. So, give it a try and let your creativity shine!
Creating an Animated Progress Bar
Progress bars are a useful tool for visually representing the completion of a task or the progress of a process. They provide a clear indication to the user of how far along they are. In this article, we will explore how to create an animated progress bar using integer variables and character arrays.
Setting the Fill of the Progress Bar
To begin, we can set the fill of the progress bar to be 100, which will fill it all the way to the right side. Additionally, we can change the label to state “progress hundred percent”. Restarting the simulation at this point will show the progress bar and label in their new states. However, in order to achieve animation, we need to introduce a new integer variable called “progress”.
Animating the Progress Bar
The “progress” variable will be set to 0 initially. We can then use this variable to dynamically set the width of the fill rectangle of the progress bar. As we increment the “progress” variable, the fill of the bar will increase accordingly. For example, when the progress reaches 100, we will reset it back to zero.
If we restart the simulation now, we will observe that the fill of the gauge is animated. However, the animation may seem slow due to a delay of one second between each frame. To increase the speed of the animation, we can remove this delay. After removing the delay, we can analyze the animation and decide if it suits our requirements.
It is important to note that removing the delay will result in a faster animation, but it may become too fast for the user to comprehend. It is advisable to find a balance between speed and visibility to provide a smooth and easily understandable animation.
Changing the Value Inside the String
In addition to animating the progress bar, we may also want to change the value displayed inside the string. To achieve this, we will need a new variable, namely a C-style string. A C-style string is essentially an array of characters. Let’s call this variable “buffer”. The size of the buffer should be able to accommodate all the individual characters we need.
By manipulating the “buffer” variable, we can dynamically change the content of the string within the progress bar. This allows us to display different values or messages based on the progress of the task or process.
The Importance of Displaying Progress
When it comes to programming and developing applications, displaying progress is crucial. Whether it’s a file download, a loading screen, or a task completion, progress indicators help users understand the status of an operation. In this article, we will explore how to create a progress bar and display it on an OLED display using an Arduino.
Creating the Progress Bar
To start, we need to allocate some space for the progress bar and determine the value to be displayed. In this example, let’s allocate 32 units of space and name our variable “progress.” Using the S print F function, we can easily set the value to be displayed as “progress” followed by a percentage sign.
Using the Buffer
To add the progress string and the variable value to our buffer, we can utilize the drawstring function. By including the string “progress” and the variable name within percentage signs, we can retrieve and display the value. However, keep in mind that the percentage sign symbolizes the variable retrieval. Therefore, if we want to display an actual percentage sign, we must input two percentage signs instead.
Testing the Progress Bar
After incorporating the necessary code, it’s time to test the progress bar. By restarting the simulation, we should observe the value changing in real-time. However, if the percentage sign is missing, it needs to be added within the string, while still including two percentage signs to represent an actual percentage sign.
Implementing the Progress Bar on Arduino
Finally, it’s time to try the progress bar on an actual Arduino board with an OLED display connected. When uploading the code to the Arduino, you will notice the progress bar animating smoothly on the OLED display. This helps ensure that users can track the progress of a task or operation effectively.
Displaying progress using a progress bar is essential in programming and application development. By correctly implementing the progress bar and utilizing the appropriate functions, such as the S print F function, you can create an engaging user experience that keeps users informed. So go ahead and use these techniques to enhance your projects and make progress tracking a seamless process.
