I've always loved automation equipment! A grade school trip to a museum with a marble machine using pneumatics, sensors, servos and more had me hooked.
Combining Arduino's with mechanical devices and machined parts is just amazing. I'm working on a project using a stepper as a "feed device" and wanted to make a video experimenting with various ways to control the Arduino Stepper as well as measuring to see just how accurate it could be!
