Art


Posted on Feb 6, 2014

A 3-dimensional LED cube, which I can program, to create Art. No more `Doug Stick Figures`, but something really cool. Follow along as I create Art. I looked through my parts bins to see if I had any microcontrollers left over as I was planning on doing the design around what I had. I found a PIC16F688 and was a little disappointed as it is not the best microcontroller on the planet, but the challenge is alway good.

So the core of this project will be this microcontroller. Its a start right As I have not done much with LED`s, other than to use them in circuits as a means of communicating whether the power was on or off, or what state the computer program was in, it was time to turn to google. After a short google search, I decided that the best starting point would be the datasheet on the PIC. While I was reading that I would have to continually eat tacks to stay awake and surf the net to earn the courage to come back to RTFM. A design was starting to form in my mind and I thought of a real simple circuit. I read some more datasheets, specifically on the STP16CP05 and finished the PIC datasheet and WHAM! Simple solution. Not really. I read for days and found this guy on web who really explained the core mechanics. Once the circuit was drawn I went into Eagle Cad Software to complete the circuit board. Everything tested out and the design was sent out to the PCB shop. While waiting for that I decided to tackle the tedious work of soldering together the actual LED cube. This part is very important as you need to ensure that the cube is really square. Not only that, there are a total of 125 LEDs in this project, so its a good idea to test everything as you go. To make sure that the cube would be square I made a jig out of 3/4 inch MDF board. I drilled 5mm holes for the LED`s and here is the final jig. I built the cube row by row. Once a...
