Hi folks,
I am using this circuit using 595s:
http://arduino.cc/en/Tutorial/ShiftOut
If you scroll to the bottom, you see where he adds a second set of LEDs. My project has four sets of LEDs. I have gotten that to work just fine. My question is that I want to have one of those sets power three "ultra bright" LEDs from each leg of the output.
This is the datasheet for the LEDs I have. They draw 50mA each. So wired in series each leg of the shift register would need to output 150mA I think.
Is there a chip I could use to replace one of those 595s that would work? Should I be wiring those LEDs in series?
The reason for the bright LEDs is these are for stage use and are under translucent rubber. Yes I need them that bright. Thanks!
