S.O.S. LED Flasher Schematic Diagram
I looking to find an electronic schematic of a small LED flasher circuit that
flashes an S.O.S. light code. 3 short flashes, 3 long flashes, and 3 short flashes, than a 5 or so second delay, than repeats.
Hoping to us a 555 timer IC.
This is for a science project for my 14 year old.
