Project description
It's made around SAMD21, w5500 ethernet chip and have one ULN2803 and 2 TLC59711 led drivers.
It's made to control a game with:
- 12V buzzers
- 12V RGB leds
- bumper switches
The game have hundreds of RGB bumpers spread in a large room, once one lights up with the right color you'd need to run to press it. And so on.
The game engine is powered by a Node.js server communicating through UDP to the ~30 boards.
Technical details:
- I use a DIY reflow oven to assemble the boards.
- I use uf2 bootloader
- I use the arduino framework
- I use platformio
Don't hesitate if you have any questions.
