This instructable will show you how to make an electronic dice with minimal experience using 7 LEDs, resistors, jumper wires, and of course the arduino (or arduino clone). I wrote this instructable for anyone to easily follow along and learn more about the arduino. Questions are welcome and will be answered as soon as possible. For less experienced users the code for the arduino is in “longhand” and several comments are included for better understanding of the code being uploaded into the arduino.

In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and program and it is a good way learn how to multiplex.

After making a 8X10 matrix a lot of people asked me about expanding the matrix to some thing bigger, and some wanted to write stuff to the matrix via a PC, so one day I looked at a pile of LEDs that I had leftover from a LED cube projected and I decided to make a bigger matrix with all the things people wanted.

So what are you waiting for? Get those LEDs out and heat up your soldering iron because we are about to make a 24X6 LED matrix!

Yes, I know this has been done before, but I wanted to build my own, using as few parts as possible. I built this as a table top or wall mount model, but it can be scaled up to make a coffee table. I built it as a study for a more ambitious project, which will be an 8×8 RGB coffee table. In designing this project, I wanted to keep the part count and cost as low as possible, and also to design the software for speed and minimal memory usage.

A quick Electronic Design I did for my girlfriend this Valentines Day, 2010. It’s just a real simple multivibrator circuit, with the Q and !Q lines fed to a couple of output FETs. [via]

Digital clocks and temperature meters are very popular projects. There are tons of such projects available on Internet. This one is little bit different. This displays time and temperature both scrolling on a 16×8 LED matrix. [via]

The LED cube 4x4x4 has the atmega32 controller and uses POV multiplexing to switch the 64 LEDS. A total of 16 transistors are used to switch on the Led columns and then another total of 4 lines to switch on or off the ground layer. So a total of 16+4 = 20 lines are needed to make the LED cube 4x4x4 work. It is important that the 4 ground layers are switched between them to switch one layer at a time and the switch the desired led’s on the particular layer.

Take a dollar-store “flickering” LED candle, add an AVR ATtiny13 and a little code, and you get an LED candle that looks almost real.
