Loublet Schematic

Ding Dong Bell circuit diagram

This is a ding dong bell schema diagram.I have attached this schema for my house.Even you can use this schema as an sound generator.When we buy this schema from the market we have to spend much money but now you can build this your self.Here I have used common Ic Ne 555 and you can operate this schema with 9V power supply.




Note

# Build this schema on a pcb

# use 9V power supply to power this schema

# When you deal with 230V be careful
