Traffic light with WiFi control

Travis Brown had a task to build a traffic light for his employer where it would indicate status of operations in headquarters. So he shares the results. This is an Arduino based controller with CopperHead WiFi shield. Lamps are driven using a custom relay board.

Traffic light status is accessible from webpage which is created using WiServer Arduino library. Light status is pooled from company’s API which keeps track of servers status. This is a great way of giving visual information and hopefully has effect on productivity.
