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 ...

The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...

The isolated analog input module ... Now we can use the “Arduino Frequency Counter Library,” which makes it possible to measure frequencies with a high resolution and accuracy. In this library, the ...

If you are looking for a project to keep you busy this weekend you might be interested in a new MIDI fader unit which is being created using a little 3D printing and Arduino programming.
