Connection Diagram In this sample connection diagram it shows how LED can be controlled via relays, while this is a bit of overkill for controlling LEDs its only meant to be an example. These relays can be used to control lamps, or some other mid-voltage range appliances.

Figure1:Controlling LEDs with one relay

The relay should have the positive wire of the device being used connected to "COM" and to "NO" as shown in figure 2, and any digital signal pin on the arduino end For example pin Sending a digital high or a "1" will trigger the relay. Sending a digital low or "0" will disable the relay.

Please be vary carful not to play with live circuits! 120V or 220V should not be taken lightly. Make sure the appliance to be tinckered with is unplugged from mains. DO NOT CONNECT IT TO THE WALL WHILE MESSING WITH THE CABLE!
