 It is the AT-Tiny 816 and the AT-Tiny 616 breakout boards with seesaw. I can program this AT-Tiny just like it's a baby Arduino. I've simply coded something that is reading button presses on this little step switch and is writing out to that LED. I've got a QT-Pi and it's plugged in using the StemAQT cable to my AT-Tiny 1616. I am running these seven potentiometers into seven of the ADC pins on the AT-Tiny. So that's able to read all of those analog values and then report them back to my QT-Pi. All I'm doing is adjusting values and showing them on this display here. You could use these up to nine of these analog inputs for anything you want on your project.
