Mount the 8-Channel Relay Driver Shield on your Arduino-compatible board. The negative ("-") power supply connection is linked to GND on the Arduino to provide a common 0V reference, and the positive ("+") power supply connection goes to the relays. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Any power you apply to the screw terminals will then be automatically sent through to the VIN input on the Arduino so that its onboard power supply can regulate it to 5V. By default it comes configured to suit R2 headers, which means that for almost all current models except the Arduino Leonardo you can plug the shield in without any changes and it will work just fine. Using a sharp knife, carefully cut between the middle and bottom pad of each set so that the tiny track is cut. Refer to the example to see it in action. Relay 1 +: Connect to the + side of the coil of your first relay. Connect from 1 to 8 channels to your relays as required. Use Git or checkout with SVN using the web URL.
