Sorry if it’s a little loud, my 3d printers running but uh hey, I have a 3d printer and actually we’ll be using it in today’s project. We’Re gon na make a we know controlled controller. For this project, you’ll need two Arduino compatible: joysticks assorted, small buttons, two large buttons, but most important you’ll need an Arduino Pro micro. These run pretty expensive, but you can buy some cheap Chinese clones for like 8.00 and if you want to build this project on a breadboard, you’ll need jumper cables and an actual breadboard. But I highly suggest mounting it to wood or, in my case I’m actually have modeled a little 3d printed, a gamepad thingy that I’m gon na mount. My project to on that note, if you just want to use a breadboard I’ve quickly made a little diagram you can follow. I’Ll also include one for the mounted version and should go without saying that, if you’re not using a breadboard, we will have to solder just real quick I’m gon na do a brief overview of each of the components and how it relates to the whole system. Because I think it’s kind of important to understand how the whole thing interconnects and functions and also I don’t – want the viewers to just blindly rely on my diagrams, because I made them pretty quickly. So yeah I’m, just gon na briefly go over each of the components. Music, alright reading from a script here, the joysticks have two inputs and three outputs joystick needs.
Five volts, which can be supplied by the Arduino boards. Vcc, pin and plugged into the joystick peg marked 5 volts or V in the ground pin needs to be connected to a ground pin on the Arduino. The joystick is composed of two potentiometers one that measures Y axis or vertical movement, while the other measures x axis or horizontal movement, both pins from the potentiometers, need to be plugged into analog of Arduino pins. The last pin is for the button which is activated by pushing down on the joystick. It needs to be connected to a digital pin on the Arduino alright, now for the buttons, both the 6 millimeter buttons and the larger push buttons are identical and function as they both serve as a switch in this circuit. Most people will insist on using a resistor when connecting a button to Arduino. However, using this code, when declaring the digital pins input, we can manage with only two wires one connected to ground and one can to the digital pin Music Music. All right, real, quick before we get into programming the Arduino controller I’ve drawn this little flow chart that represents the path the data takes start to finish from the physical controller to the game. Of course, it starts with your hands and the way you interact with the physical controller and the Arduino interprets the data from the buttons and the joysticks and transfers that to this virtual joystick that the joystick library creates and then from there.
The data goes to directly to the game or it can pass through Steam, which can configure the data for games that don’t have built in controller support all right I’m, not a very experienced programmer, but I’ll do my best to explain what’s what’s going on in the Code I’ve written here so essentially in void, setup we’re, declaring all of our buttons as input and if you’ll remember previously, I mentioned that the underscore pull up allows us to only have to use two wires. This joystick dot begin starts the whole joystick process. These all of this is basically setting up our axes, so this variable that we’ve created up top here is equal to the input from the analog pin to, and here we’re just mapping it to these things, and you could actually mess with these numbers to invert the Axes, if you prefer that and then this just sets our variable to the to the virtual axis here and then for the buttons I just used. If then else statements, I guess is what they’re called just cuz I’m, not very advanced, Arduino programmer and just a lot easier for me, but basically just means that if the button connected to well in this case pin nine is pressed, then it presses the virtual button And then, if button connected to pin 9 is not pressed, it releases the virtual button so to anybody that has like a basic knowledge of Arduino. This is pretty straightforward, but I know it can be pretty confusing so make sure to shoot me a comment.
If you have any questions and I’ll try to help you out, once you’ve uploaded your sketch to the Arduino micro, you can go to your search bar and go to setup. Usb game controllers and Arduino. Leonardo should be there. If you hit properties, it should come up with this and you’ll see, hopefully, if you’ve configured everything right, that it’ll move the axes. Well, I have to say that was one of my favorite projects I’ve ever done. I had a lot of fun and I hope you choose to go to follow along and replicate this that you have a great time too so I’m, just gon na leave you with some footage of me using the controller to play some games and I’ll throw up. My Instagram feel free to follow. I do a lot of painting and art and I post a little updates on my project, something you may have seen the painting I sent to William Osmond. That was really fun, but yeah feel free to follow me on Instagram.
