Hi all I'm new at this so I need some instruction.
I am trying to build a 20watt Bike light LED driver, multi level dimmer, single push button unit.
I have attached a rough cct diagram. Can I use a 4 bit binary counter (with amplified O/P's) to drive the power transistors?
I have tried to build this already but its a no go
Some Part #
4 bit binary counter: SN74LS93N
Amps: UA741CP
Transistors: BD679
