    Relay Connecting With Arduino

    .It is a simple project and but its also very dangerous ...

    because we are going to deal with high voltage 220v . Do not attempt if you are a amateur in dealing with high voltage.

    Why to use relay for controlling AC light,fan and other appliances...

    AC is alternating current 220v (india) which powers the ac lights,fans,cfl ets.... Arduino cannot control high volt n amp, but a relay can do this job, which is the sole design of it.

    so we are using relay as switch to control high power devices.

    What is NO NC and COM in relay?

    C = Common Connection

    NC = Normally Closed Connection

    Set Up Circuit Using Relay,arduino and Bluetooth

    here is connection...

    bluetooth is connect to arduino in tx and rx pin...

    we have to connect all appliances to relay board.....

    one relay board for one lights,then 2nd for CFL,3rd for fan and 4th relay for tubelight....

    thats it....
