Hangboard Controller is a custom physical interface emulating a Nintendo Switch controller that was developed to play EXOK's "Celeste". The custom hangboard controller works through custom-flashed arduino firmware, an arduino sketch, capacitive touch, ultrasonic data, and bluetooth. First, the controller is set up to have a number of capacitive touch buttons, with paperclips used to detect touch. Additionally, an ultrasonic sensor is set up above the hangboard to determine when I do a pull-up. The Arduino sketch on the Arduino Nano reads in ultrasonic data, to see if I am doing a pull-up, as well as capacitive touch data, to see which buttons I am holding. It would then relay these inputs over to the Arduino Uno through bluetooth connection. The Arduino Uno sketch would take this bluetooth input and write it to serial, where a custom-flashed firmware would emulate a wired switch controller, sending controller inputs through USB connected to my switch.

Project used a fork of @wchill 's Nintendo Switch HORIPAD emulator repository on Github and was developed over the course of a week.
