The gauge works well but I can't get LED from the LM3914 to light up for some reason. Either I'm not changing the right resistors or I'm total off on what the issue is.
If anyone has a suggestion I'd appreciate your help.
How are you proto-typing?
Do you have a breadboard ... or are you using a pcb?
If breadboard ... can you post a picture? Sometimes the holes that look connected are not.
