I have two sets of LEDs off the circuit...the first is an LED Bargraph driven by the LM3914 with an input variation from a POT...depending on how high the POT is turned on I measure anywhere from 40mA down to 9mA (I may be measuring wrong so let me know if these sound wacky).
I also have two...
Hello all,
Couple quick questions...this is an aside from the LED Bargraph question I asked earlier...I took everyone's advice and got the LM3914 and it worked like a charm...much better than the complex circuit I was trying to devise. My only problem now is that it seems to be draining my...
Quick question...I was wondering if there was a way to take an LED Bargraph and connect it to a knob, so that depending on the turn of the knob, a different amount of LEDs on the Bargraph would light up? If it helps, you can think of it as a volume control meter display though that is not what...
