Just a quick question on what to do with the unused LED pins on a LM3915. I'm only using 3 of the 10 LEDs. What do I do with the other 7 pins? Ground or nothing??
Thanks
 

Each output of an LM3915 is an open collector that sinks a regulated current when it has an LED or resistor as a load connected to the positive power supply. If an output does not have a load then the output does nothing and does not need to be connected to ground.
