I have the same question. I need to drive apprx. 90 LEDs to strobe at variable cycles of ~ 4 ms to 50 ms, say. (2 potentiometers, .047 uF capacitor, ground capacitor, 555 timer, LEDs @ 96, 13.8v input with current of 35 amps to supply the LEDs).
Each of my LEDs draws 350mA. Supplied by a 13.8v power supply, if I put them all in several series of 6, the voltage drop (2.3 fV each LED) across each LED will not require a resistor for the series.
Is it possible to have the positive input line run through all the LEDs before going through the timer somehow?
My circuit is going to draw 35 amps, more or less.
Do I need to find a different way to create a strobe effect?
I don't understand how current affects a 555 timer in a circuit where other components can suck up that current.
Thanks for any advice, and I apologize for being a dunce on this one.
