In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...
