Simple Doorbell



I think at present we can't see a house with out a doorbell.And also people use different types of doorbells.Today I'm going to give you a nice and simple doorbell circuit.Here I have used very common IC UM3481.And another thin is we can get different songs This Ic has the ability to generate more than 16 sounds.Normally we can use 1.5V to 3V to run this circuit.







Note: 

# Do not use more than 3V.

# Build this circuit on a PCB.

# As S1 switch use push to on switch.
