Controlling High Voltage Loads Using a Microcontroller

A while back, I had a project that required high-side switching of a set of pneumatic valves by a microcontroller. Because the loads were inductive (solenoids) and required a good deal more voltage than the microcontroller supply to activate (24V), I needed some kind of middleware between the Arduino and the valves.  I created a…
