It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something ...

This online lab demonstrates a control system that uses an Arduino-based setup to levitate a ball in the air and maintain its position using a PID (Proportional-Integral-Derivative) controller. The ...

The pluggable discovery specification and platform specification describe how board definitions can give a board's USB VID and PID, or more generally identifiers. This note is given: The Arduino ...
