RuthJ180 produced this video of her using the the Arduino relay driver to control a doorbell:
On the page where this video was posted RuthJ180 referenced these two sites:
- An article from Maurice's Hobby Robotics "Using Relays with Arduino – Turning on the Lights": http://www.glacialwanderer.com/hobbyrobotics/?p=9
- And here is the schematic she used: http://www.arduino.cc/playground/uploads/Learning/relays.pdf
Any ways, I hope you all have a great weekend ~ Jim
