Binary Clock using LED Matrix module (8x8) and presenting many features: time, date, day of week, week of year and also the Moon phase!

Everyone loved Knight Rider. I want to see more KITT scanners in the world.

An alarm that triggers a siren sound an police lights when the beam of light is interrupted.

A 3D-printed snowflake made with Arduino Uno. Has 91 addressable RGB LEDs.

Use your Arduino to create a Binary Clock and learn how to read Binary numbers.

We will use 4 LEDs, depending on the level of light that we capture with the LDR sensor.

This is a simple IR sensor block detector for model railroads. It controls three lights: red, yellow and green.

4 RGB LED's That blink In A Row Of Colors

Ambientlight for Raspberry PI and Kodi

This Arduino library is for controling RGB LED colour and fading between colours.

Simulated snow on a line of LEDs wrapped around a tree

Learn how to make a 3D-printed RGB lamp using a WS2812 LED strip.

These libraries for a torch can do different functions. Each version is similar to each other with updated functionality and control.

It came with only an on/off switch. Adding an UNO to this LED chalkboard really gets your attention - it is quite a flashy pig.
