Arduino Ins and Outs
The Arduino is a microcontroller board that serves as a bridge between the physical world and the digital world. It is capable of taking inputs from sensors, switches, and other devices, and outputting signals to LEDs, motors, and other devices. This makes it an ideal platform for a wide range of projects.
The Man in the Middle
The Arduino acts as the “man in the middle” between the input and output devices. In our example, the Arduino is watching for an input from the switch on pin D2. When it detects a change in the input, it sends a signal to the LED on pin D3, causing it to light up. This is accomplished through a bit of programming, which tells the Arduino what to do when it detects a change in the input.
Programming the Arduino
Programming the Arduino is relatively straightforward. It uses a language called C++, which is similar to other programming languages like Java and Python. The code is written in a text editor, and then uploaded to the Arduino board. Once the code is uploaded, the Arduino will execute the instructions whenever it detects a change in the input.
Making Connections
In order for the Arduino to detect changes in the input and output signals, it needs to be connected to the devices. This is done by connecting the devices to the Arduino’s pins. The pins are labeled with numbers, and the code tells the Arduino which pins to watch for input and which pins to send output signals to.
Arduino Ins and Outs
The Arduino is a microcontroller board that is used to control and monitor a variety of devices and systems. It is capable of both input and output operations. Input operations involve the Arduino monitoring and detecting changes in signals from external sources, such as a switch or a sensor. Output operations involve the Arduino sending signals to external devices, such as an LED or a motor.
The Man in the Middle
The Arduino is the “man in the middle” between the input and output devices. It is responsible for interpreting the input signals and then sending the appropriate output signals. In order to do this, the Arduino must be programmed to recognize the input signals and respond with the correct output signals.
Pin D2
In this example, the Arduino is monitoring pin D2. This pin is connected to a 10K pull-up resistor, which is holding the pin at 5 volts. When the switch is pressed, the 5 volts is shorted to ground. The 10K resistor prevents any damage to the Arduino by not allowing a direct short.
LED Circuit
The output side of the Arduino is connected to an LED. The LED is connected to pin 3 of the Arduino, and is connected to ground through a 470 Ohm resistor. When the Arduino receives the input signal, it sends a signal to pin 3, which turns on the LED.
