The AVR-Circle
is a little AVR-project just for fun, based on the ATMEL AT90S1200
microcontroller. You will see a nice little lightshow.

The schematic: In the schematic you will find the AT90S2313. You can
use it but the AT90S1200 is cheaper and it works as well as the other type in
this application.
The layout: Download in postscript
(17KB) The resistor R16 and the capacitor C1 are missing in the layout.
Please cut the line to pin 1 of the controller and insert these two parts.
Otherwise you may have problems with the reset of the controller. You should
provide a diode to prevent wrong polarity of the power supply.
