Mini Stoplight (Programmable ATTiny85 Arduino AVR) by Montiey

Last crawled date: 4 years, 1 month ago

This mini stoplight runs on an ATTiny85, or other small MCU chip. The circuit is very simple, and is easy for any beginner to build. You can power it from a wall wart (Be careful! I burnt out 3 of them trying), or a suitable battery pack.
