Simple Arduino Stoplight Controller

This project like the name hints is just a very basic controller for a stop light, I used an arduino but in reality that was overkill this could easily be done with an ATtiny.

Step 1 Supplies

• Stoplight (i got mine from an uncle.... i didn;t ask where he found it :P)
• Microcontroller(i used a RBBB arduino board from modern devices)
• Standard wall outlet and plastic enclosure for outlet
• Relay board(you can either make this or buy one premade from ebay for ~$10
• Hookup wire both light gauge(arduino to relays) and heavy(relays to lightbulbs)
• power supply for microcontroller
