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.

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.

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.

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… ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...
