Miniature Traffic Light System using Atmel AVR (STK500)
This project uses basic LED’s to serve as traffic lights. A phototransistor is used to detect incoming side traffic and also a Ping Sensor is used to detect if any cars are sitting at the light. The main road also has a timer display to let incoming traffic know when the next transition is going to occur.
