I've now added the gerber files (and .pdf files for anybody who wants to have a go by the toner transfer method, or similar). The aim of this board is to provide...

It will help if you have some experience in any of the following areas: chemistry, PCB etching, avr programming, writing simple C programs, and / or soldering (surface mount soldering). If you don't then the trickiest part will be the soldering since i...

I did not write the code only made an Eagle PCB for it. http://www.daqq.eu/index.php?show=prj_game_of_life An error on the schematic I followed the schematic provided on the site only to realise the Backlight LEDs where inverted. Anyway for th...

How to drive a lot of LEDs from a few microcontroller pins. - More DIY How To Projects]]> http://cdn.instructables.com/FDR/41GC/8RYEP27Y2FY/FDR41GC8RYEP27Y2FY.SQUARE2.jpg http://cdn.instructables.com/FDR/41GC/8RYEP27Y2FY/FDR41GC8RYEP27Y2FY.SQUARE.jpg http://cdn.instructables.com/FDR/41GC/8RYEP27Y2FY/FDR41GC8RYEP27Y2FY.SMALL.jpg westfw Using the fact that many microcontroller pins have three states (+V, GND, or"high impedence", you can drive N*(N-1) LEDs from N pins. So the little 8pin microcontroller like a PIC12Fxxx or an ATtiny11 can drive 20 LEDs onits five available output pins, and still have one pin left for some kind of i...
