One Challenge with working with RGB LEDs is getting the right Red, Green and Blue values to match a color you are trying to display. You can start with web colors, and then sometimes need to adjust them since the LEDs don’t look quite the same as they do on monitors. So, this is a […]

Introducing the RainBoard: A simple RGB LED Rainbow fader using an Arduino Uno and a few simple components. Believe it or not, we will control 45-channels of RGB LEDs at 32 brightness levels using only 3 digital pins from the Arduino! How is this possible you ask? By using two magic concepts: Shift Registers, and

A while ago, when I first started using Arduino, my first project was a 4x4x4 LED cube, I built it from a Guide I found here in Instructables, I didn’t know anything about programming, and little about electronics, yet I was able to build it and make it work, I didn’t know how it worked
This Instructable covers the assembly of a circuit capable of PWM-ing (pulse width modulating) a high-power RGB LED strip and programming an Arduino to cycle through a range of colors. In this context, “high power” is 9-12 volts. I will discuss how to mount a transistor to a heatsink and assemble the circuit. I will
As hard as it might be to believe, I had never built an electronic clock of any kind. I’ve always thought electronic clocks were passe and not worth the time to design and build one. In addition, I thought that all interesting electronic clocks designs had already been built so why bother building an also

This display is based on an 8×8 RGB LED Matrix. For testing purposes it was connected to a standard Arduino board (Diecimila) using 4 shift registers. After getting it to work I permatized it on a fabbed PCB. The shift registers are 8-bit wide and are easily interfaced with the SPI protocol. Pulse width modulation

I just happened to see some large strips of LED lighting when I was picking up some parts at Maplin which were on sale (if I remember correct they were around £12 per approx. 2m strip) however the controller/driver was still around £40, so I thought I would just build a better one myself. I
Here is an easy(enough) project to introduce you to the Arduino microcontroller, as well as Processing. This is my first Arduino and Processing project and I didn’t have too much bother getting it working. This is my entry to the Sparkfun Microcontroller contest so if you think it’s good, please vote!!(voting starts the 14th feb).
DIY RGB Tube light is a multi functional tube light which can be used in photography, light painting photography, film making, gaming, as a VU meter and more. The tube light can be controlled by Prismatik software or by a push button. These tub lights are made using a Arduino Nano and WS2812B LED strip.
Continuing with ATtiny85, today I’d like to share how to build a music spectrum analyzer on 16×20 RGB led matrix. The music signal FFT transformation and LED Bit Angle Modulation are all carried out by one DigiSpark ATtiny85. Please watch my video below: Step 1: Things We Need Main components are as follows: 1 x DigiSpark ATtiny85.
