My 3V Ultra-bright Chaser project lights red LEDs brightly for months, and still works when the battery has dropped to only 2V.
I selected low voltage ICs for the projects. It can be completely re-designed to use higher voltage ICs.Any mods needed to make it 12v. ??
You can connect as many LEDs in series and driven from each output pin as their total voltage and the supply voltage will allow.AND - will it be possible to run two LEDs off of 2-3 pins instead of just one ?
