Circuit Documentation
Summary
This circuit consists of a 16-channel analog multiplexer, multiple rotary potentiometers, pushbuttons, resistors, and an 8-channel multiplexer. The circuit is designed to read analog signals from the potentiometers and digital signals from the pushbuttons, which are then multiplexed for further processing.
