Please help me come up a SIMPLE solution to this problem.
I already have a simple circuit that is activated by sound, which beeps and blinks a small led.
I would like to use the 1 vdc that is lighting the led to switch on (and off) a 12 vdc circuit that will be used to light a more powerful LED
I keep hearing NPN, but I sure could a simple schematic which would give the transistor that I could use, along with the values of the other components.
thanks,
