Hi
folks i have bought a door bell to replace my automobile horn ( that consumes too much current) for my prototype alarm system.The door bell uses an input voltage of 4.5VDC.The transformer presently i have uses 12VDC .
I have read that a zener diode can be wire in series used to limit the voltage to 4.5V.There is very little information on the net about how to achieve this end.
Has anybody ever tried hands at the zener diodes?I need a little help.
