Description

The Winky Lights Redux Project repeats the original PIC based design with an 8 pin AVR ATtiny85.

It uses 5 I/O lines to drive 20 LEDs using differential LED connections (Charlieplex). The code uses a display buffer and a position tranlator to simplify wiring. The basic pattern is stored in Flash and can be modified in the buffer for dynamic action.
