[Jon] will be tapping away with his toes during gaming session thanks to this foot controller which is packed with buttons and sensors. Itís the second iteration of the build. The original had some solder joints break and the USB stopped working. He had also been experiencing some erratic behavior and so he decided to upgrade the control hardware and add a few more things in the process.
This version uses an Arduino Uno as the interface board. He did a bunch of prototyping to find the best way to hook up all the analog sensors, and how to properly debounce the buttons. Once he was happy with the inputs he set about finding a better way to use the USB HID standard with the device. We were surprised to hear that the ATmega16u2 (one of the new AVR chips which includes USB hardware) doesnít play nicely with Linux. But [Jon] managed to hack his way around that issue and now heís gaming with an even better foot controller than before.
