Step 2: Build the Circuit

Picture of Build the Circuit
Following the schematic, make the connections between the rectifier, diode and relay. You will need to bench test your relay to determine the input and output connections as well as the )+) and (-) connections on the rectifier.

You will end up with 4 open wires. Two coming from the relay and 2 coming from the rectifier.

NOTE: My doorbell circuit generated 18V from the transformer with 13.5 volts AC at the doorbell ringer. Your doorbell voltages may be different and the circuit may have to be designed specifically for your voltages.

Key Kip, The schematic is ok in the instructable but wrong in your video on youtube! Cheers!
