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.

This is a tool that allows you to control your Arduino pins with your serial-console. Typing in read or READ will ask you for a pin number and then will return the current state of this pin. Writing ...

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 following is excerpted from the ...

All by itself, a calculator based on an Arduino isn’t necessarily very novel. However, [Danko Bertović] of Volos Projects has a nice board that, of course, looks like a calculator. There are 16 keys ...

Need to quickly toggle or read some logic signals without the hassle of writing a quick program? [Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to ...

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 boards ...
