This is kind of a uDirect type game by Cory "Mr. Safety" Williams , Great idea.
My First Arduino Project - 4x5 Charlieplexed 20 LED Array
Over the past months, i have been buying kits from Maplin (like RadioShack only British) a few weeks ago i bought a box of 6 kits in a clearance sale, with the intention of building the kits on solder less breadboard instead of the PCBs supplied. I had mixed results possibly due to me making a very stupid error where I didn't understand the IC pin out conventions. I also found an old electronics kit i bought years ago, and kept at the bottom of the cupboard, it had loads of IC's and some books. I suddenly realised I had a decent parts bin, and a lot more drive than when I was younger.
I decided to buy an Freeduino (see my last post) and looked for a project. I had loads of LEDs and from reading lots of making things sites, I knew Charlieplexing was the way to go. I read up on Charlieplexing theory and built a 2x3 array connected to 3 IO pins. I found a Instructable on making a Charlieplexed heart, and borrowed the source code and I adapted it to 3 pins. I don't know much about coding (yet), but the code was easy enough to understand. It worked, so i built a 20 led array out from 5 IOs which was the best layout for my breadboard. I reloaded the heart code, and found that not all theLEDs worked. Because the code was for 27 LEDs from 6 IOs it should have been suitable for 30 , but he had left out the unnecessary (for him) code. So I cleaned up the code, and made the LED's programmable in a human friendly order (is it is no no longer a heart). Anyway, here are the results.

Got My First 'Duino, and a few days later...
A week ago I got a freeduino from a seller on e-bay. A Freeduino, for those who do not know is an Arduino clone, which is a small open source "computer" designed to control and receive feedback form the real world. Alas yesterday, a new member of the 'duino family was released, the Sangiuno (pictured) with even more power.
Anyway, I am enjoying the freeduino, and will not get jealous over the "new model". My real purpose is to learn all about electronics, be a bit creative andmaybe take over the world with the army of robots I plan to build just share my journey and cool stuff i find along the way. My first project is coming very soon, and expect some talk about comics my my later blogs too.
