After a lot of debugging on bbvablogs.com, I needed serious fun to keep it up, and suddently I found the perfect project to remove the dust on my arduino board: a blinking led that would tell us when someone is visiting the website!
After a first try with tiny space between LEDs (see last post), here is another try with enough space to build a proper cube, still following MakeZine instructions.
The fun parts were to add transistors to the board, allowing to get more power for each led level, and the programming: Persistance-Of-Vision and binary manipulation for led on/off switching.
The original project for tonight was to build a 3D LED cube, and the not-so-clever idea was to compact it the size of a normal dice.
Big mistake: first it was hell to solder all the tiny intersection of led cathods, then there is no way to pile up the array of leds if you don’t let space between them… maybe there’s a solution to that, and I’ve not find it yet.
Anyway, it was ready to connect to Arduino board, and to try to program this new led-matrix. Easy and fun, only problem is debugging messages while verifying source code on Arduino software that doesn’t help much, I’ll have to learn more about its syntax limitations.
Here is the result, 5 days before returning to Toulouse to visit Claire:
