The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

This project turns on and turns off a laser LED after every second. It can also monitor its own supply voltage level. It uses KY-008 Laser LED module.

These addressable LEDs can be easily controlled by an Arduino. So, in this Arduino inerfacing tutorial series, we are going to look at how to interface such LEDs with Arduino. We will be interfacing ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...

LED Control: If the RFID tag is recognized, the LED toggles its state (ON or OFF). If the tag is not recognized, access is denied, and the LED state remains unchanged. SPI Communication: The RFID ...

You may remember [michu] from his StripInvaders and PixelInvaders projects, basically a few RGB LED modules that can communicate with an Arduino over an SPI interface.
