In this project text is transmitted between two arduinos by using a LED and a LDR.

A simple gesture-controlled interactive table light, which can encourage kids towards making.

Card access with pixel feedback, red for wrong, green for right.

Use LCD Screen to Display Received Code through Remote on LCD and assign Different Character

Simulate a traffic light using an Arduino and LEDs! This project is super cool to watch and easy to make!

DIY light based transmission between two Arduinos using LED and LDR with custom communication protocol.

We Will Build Two Types of Matrix Displays with Arduino and ESP8266.

Control a led strip with an ultrasonic sensor, set the color with your hand, or switch modes and let the music control it!

Sending Bytes to an 8x8 LED Matrix.

Set up an RGB LED to phase through the colors of the rainbow, or use twist knobs to make a custom color.

An animated cube made with 512 RGB LEDs driven by an ATmega328.

Let's create a light gate using Arduino.

The task was to control a lighting system with an Arduino via DMX.

LED emergency lights for use on model / toy vehicles and other projects. Uses Arduino UNO and GY-WS2812B-8 RGB LED Module from DIYmall.

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

let's build a custom Arduino compatible 8*8 led matrix

Using opto isolation chip to control neon lamp (nixie tube) by Arduino UNO. My first experiment for the way making nixie clock.

In this project, I’ll show you how you can build your own mood light. You’ll use an ESP8266 to remotely control the color of your light

Anyone can go to the store and get flowers! Use an Arduino and some lights to make them magical!

Using LEDs as Binary No. and 2 button switches to add or subtract 1 point per push.

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

You'll learn how to create a display led to print message through Bluetooth.

This is my project about an Analog Clock on a LED matrix and Arduino.

A simple Advent Candle controlled by Arduino (various light effects and also plays "Jingle Bells" upon button press)
