Make your own light up button controller with Trellis, Adafruit open-source button platform. The trellis is designed to work with any kind of arduino boardYou can connect your controller to your computer with the Arduino USB portYou can get the parts and tools for this project on adafruit. comCustomize and 3D Print our enclosure to fit your controller. We’re making a basic 4x4button box – its small and handheld!Our 4-piece design fits the Trellis PCB, elastomer Buttons, and an Arduino. You can decide what color LEDs you want to light up your buttons. Solder them in, anddon’t forget: The long terminal pin of the LED goes into the positive pins. Trellis will multiplex the LEDs with constant current, so you can mix up your 3mm LEDs colors!Solder the 16 LEDs to the back of the Trellis PCB, then trim the legs with diagonal cuttersTo connect the Trellis to your arduino, use 4 jumper cables. We want the kit to be compact so we removed the plastic guards, you can also just useplain wire. The trellis pcb and buttons tightly snaps onto the printed tray. The tray is designed to expose the wire connections so they can pass thru to the ArduinoThe bottom cover includes mounting holes for the arduino. You can use an Uno or Leonardo,use two or three screws to securely mount it. The printed frame has holes for both power and USB – but you can use USB for both powerand data. Now it’s time to close up: carefully bend the four jumper pins to fit into the enclosure. The outer has a lip that secures the top above the arduino. Once you have placed the elastomerkeypad on top, you can snap the cover on. The trellis can make a great musical instrument, custom keyboard or light up game. What awesome project will you come up with? let us know by joining our weekly show andtell. Thanks for watching and don’t forget to subscribe for more projects from Adafruit.
