Wiring an LED Bargraph to act as a meter
Wiring an LED Bargraph to act as a meter
(OP)
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 it will be used for. I am having trouble figuring out how to get voltage to the different pins for the different LEDs at the same time based on some type of turning knob. If anyone has any thoughts or knows of any other components that would be better to achieve this goal that would be greatly appreciated. Thanks!

Also have a look at M5450B7 from ST Microelectronics, available from the same source.
