Hi all,
I'm planning to recreate this sequential turn signal circuit:
... and actually use it in a custom LED turn signal assembly. Problem is, apparently the 555 is only rated to 200mA, whereas my proposed assembly will draw 1.33A @14V with all LEDs powered (19 arrays of 4 LEDs, each with a forward current of 70mA - 76 LEDs total).
Is there any way I can get around this and provide enough current for the LEDs? Also, is it possible to just add on strings of LEDs to this diagram so that there are 19 steps instead of 5?
I'm a novice when it comes to circuit design, just hoping to make sense of it enough to create this circuit.
