This tutorial will guide you through creating a DIY Piano RGB LED Visualizer using Arduino and WS2812. No professional tools are required, making it a great project for beginners. Connect the data pin ...

Connect the four LEDs to Arduino digital pins 7, 8, 9, and 10, each with a 220Ω current-limiting resistor connected in series. Connect the other leg of each LED to a common GND pin on the Arduino.

If you do it in hardware though, you’ll gain a lot more than coding skills. Just ask [Kelly] and [Jack] did, when they built this Arduino-based electronic Connect Four for a school project.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Connecting Arduino to Processing Introduction So, you’ve blinked some LEDs with Arduino, and maybe you’ve even drawn some pretty pictures with Processing - what’s next?
