My 2µF

To all You LED aficionados out there:
I’ve started a new photo group on Flickr aptly called ‘64-pixels’. It’s intended to deal with strictly anything having 64 pixels. Currently it is fed by pictures showing the various 8×8 LED matrix devices that are out there. The ‘Meggy Jr.’ AVR DIY gaming device by Evilmadscientist is among [...]

I’m happily awaiting the prize ;-) Now I’ll finally be able to learn to work with AVRs “the right way” (LOL). For links to the other awarded projects, just click here.
“myAVR MK2 USB PLUS” development KIT – kindly sponsored by myAVR.de, have a look. I’ll report my findings when I find some time, once the [...]

Hi again!
I really can’t believe it myself, but it works just fine ;-)
All of this is coded in Perl and is only tested on linux. The program uses these modules, if you don’t have them install from CPAN as root. You will need a working version of GCC + all the libs installed.

OK, enough with this pompous title.
I’ll just show how to hook up a normal potentiometer to PORTC, PIN2 of the ATmega168/328 microcontroller and control which image is displayed on the matrix. This pin works as an analog to digital converter. In Arduino language, this is the “Analog 2″ pin, which is referred to in the [...]

It seems I’m by far not the only one fascinated by LED matrices.
Interactive-matter have put together an overview of 64-pixel projects. Go and have a look :-)
