Arduino Temperature Sensor Kit
passive brake light
In this application the relay is needed to allow more electrical energy to power the brake lite. You can use the Digital 5 pin on the arduino as a trigger to anything. If you had an LED connected to the Digital 5 pin and ground it would light when triggered. Hope that helps. Thanks for looking!
