My intention is to have a small circuit board that can either be used as a torch or through a program in the PIC will flash the SOS code.
The programming side is no problem. I've got that almost done.
The area I need advice on is how to power the 10mm LEDs. They require 30mA each and have a forward voltage of 3.3V. I would like to power the circuit off a 9V battery. Is the use of the positive logic mosfet suitable?
My intention is that 9V is used to power the LEDs but 5V powers the...
