This week I have been working on the detection circuit since the multiplexer arrived. I am able to loop through the inputs and will soon scale it to use all 16 inputs, adjusting the resolution as needed. Once the 16-piece detection circuit is working on the breadboard, I will begin construction of the board top or construction of the pieces, depending on when the pieces ordered from Amazon arrived. I mention wooden pieces because, as of our design revision, we will now be modifying wooden chess pieces instead of 3D printing our own.
Below is an image of the arduino console detecting input from 3 “pieces”, where 14 and 15 were set to GND and 16 was set to an arbitrary voltage <5V:
I am behind our original schedule but proceeding well into the adjusted schedule.
