![]() Each switch will require one pin as well (12) and I think each LED will require one as well (12). ![]() Your encoders alone would need 10x3 digital pins (30). I used the AMstudio button box code but removed all the joystick code and replaced with serial printing of keyboard scan codes. The encoders required a separate procedure for determining clockwise and counterclockwise motion and the A and B channels required each a digital pin. I used a keypad matrix wiring diagram for all the buttons except the encoder switches which I read from one of the user comments on the product page, that the switch cannot participate in a matrix ( Apparently those encoders without breakout boards can ) so I used a digital pin for each. Unojoy library only has a limited number of buttons and I needed about 20. It inspired me to create a button box for ATS using an arduino uno. So far, I haven’t found a way to map the LNAV, VNAV, and FLCH autopilot buttons.For future projects, I’m going the printed circuit board route.Be sure to watch a few videos on how to use the crimping tool with the Dupont connectors.I used Fritzing software to keep track of where all the wiring was going.The mini breadboard came in handy to connect all the ground and power wires.The pre-wired switches and LEDs come with all the capacitors/resistors needed you only need to wire them to the Arduino. Be sure to watch the Arduino tutorials to see how to wire up the switches and LEDs.Be sure to use a center punch to keep the drill bit from wandering off. This was my first attempt at an electronics project. The best thing about this project is that I found a great new hobby – electronics! Those Arduino boards are too much fun! The board was programmed using the incredible no-code software from .Īnd that’s it. I drilled a bunch of holes in the box lid using the printout as a guide, mounted the hardware, and wired them to the Arduino board. The site offers professional fabrication services for a good price, but I went the DIY route and printed the design on a transparent sticker film and stickered it to the aluminum box. The panel was designed (drill holes, cut-outs, text labels, graphics, etc.) using the free Front Panel Designer software from. Wiring: Dupont crimping tool, male/female connectors, and ribbon wires. ![]() Mini push-button switches (mountable) with pre-soldered wires.Mini toggle switches (SPST) (mountable) with pre-soldered wires.I used the ones attached to breakout boards. Rotary encoders (mountable) with push-button action and knobs for Arduino.Mini breadboard to connect ground and power wires.USB 2.0 printer cable to connect Arduino to PC.So I figured if racing sim fans can build a “button box”, flight sim fans can build a “knob box”. I had difficulty using the mouse to turn all those panel knobs in-flight with the aircraft bouncing around. ![]()
