Hello, I need a circuit that will run on 9VDC. It's function is to page by (light & sound) 3 seperate remote boxes. It must be activated by toggle switch.
It needs 3 outputs, enough to drive (3) separate piezos. Also, each output will have a bright LED and a potentiometer to control the volume of each piezo.
As I am pretty new to electronic design, I really need as much help as possible including an example wiring schematic and values to use for resistors, LED's, etc.
Thx in advance..
