This project enables individual control of an array of 8 LEDs using an Arduino Uno. Each LED is connected to a separate digital pin on the Arduino, allowing for versatile light patterns and displays.

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.

RASH (Robot Arm Servo Harness) – Arduino firmware for a custom servo harness that attaches to the EVA robot arm end-efector. The firmware interfaces between the two GPIO pins of the arm and an array ...

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.

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 ...

[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… ...
