PROFC (Cheap Generic LED Sequencer MKI)

Description:

The Unfocused Brain - PROFC (Cheap Generic LED Sequencer MKI)

This program and schematic is designed to flash LED's in sequences depending on the setting of jumpers or switches.

It was designed for Professor Conrad of Flim Flam Laboratories

The most important goals of this project were to make it cheap and easy to build. The chip (attiny22/44/84) costs about $2.15 in one off quantity and can be as cheap as $1.42 in qty 100.

I chose the attiny84 as the brains for this project because it is small but not too small. It has 14 pins only 11 of which can easily be used without any modifications of the FUSE settings. So 8 for LEDs and 3 for jumpers/switches.
