How to operate Ac with Dc

Most of you requested  circuit diagrams to operate Ac circuits via the signals of Dc circuit diagrams .So Today I'm going to show you how to how to operate Ac unites via Dc signals .In this work Most common way is using a Relay,Here I have used 5V relay you  can chose your relay according to the voltage of your Dc circuit. If you want you can add a Fuse for the load.Through this method you can control various types of light circuit diagrams.By using this circuit diagram you can control 12V unites too.that means you can give 12V power instead of 230V and as a load you can use 12V unit.

Note:

# Build this circuit on a P.C.B
# If you are a child Don't try to build this circuit diagram because 230V is dangerous
