Automatic Voltage Contoller request

Not open for further replies.

Hello all! :D

I was wondering if anyone had a circuit for an automatic voltage controller where pressing a button (or flicking a switch) would slowly increase the voltage up to 12 volts. Pressing the button (or flicking the switch) would then drop down the voltage again.

I live in Australia so if you can, could you also list any alternative components like transistors, ICs, etc.

Thanks a heap :p
