The board layout and the source code is all available on GitHub. Because the switches are analog, they are bidirectional. That is, it isn’t really connecting one output to 32 inputs.

The voltage divider decreases the voltage being measured to within the range of the Arduino analog inputs. Code in the Arduino sketch is then used to compute the actual voltage being measured. The ...

However, the simulator does not save the source code in the virtual Arduino ... is exactly equal to the input even if we could define what that means for an analog signal. So we have to measure ...

Electronic engineers, developers and hobbyists looking for a fully featured Arduino Mega compatible ... It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V ...
