This is a step towards creating a prototype of a capacitive sensor (Issue #3) but does not close it yet, until an FPGA version has been written and tested
This is great work @redchillipadi. I have found this repository that achieves something similar to our goal https://github.com/stnolting/captouch. We will be able to utilise some of the code in there. I will perform more research and testing on circuit design for the capacitive sensor.
There is a great how-to guide in that repository. We can use that as a starting point for our sprint 2. I will continue circuit research and extend the touch functionality to proximity functionality.
Proof of concept for an Arduino based capacitive sensor.
Connect pins D2 and D3 from the arduino to opposite ends of a 10 MOhm resistor on breadboard Wrap a piece of foil in glad wrap and put one end of a dupont wire through it (so it touches the aluminium), and the other end connecting to the 10 MOhm resistor (on the pin 3 side)
