There’s also a button to toggle settings, and two lamps to show what mode the motor is currently in. The Arduino runs a finite-state machine (FSM), ensuring that the device transitions through ...

What’s really happening is that an Arduino is getting a signal from the toggle switch, and is then rotating it on a ball bearing with a stepper motor driven through an H-bridge.

Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave Darko. That requires users to ...

C ‘common sense’ is that the switch/case answer is both faster and makes more compact code because compilers tend to convert these into a jump table. However, the Arduino compiler tends to convert ...
