Testing the circuit:
If I isolate pin 3 of the LM3916, I stop getting voltage readings on pins 4 and 5. This to me indicates that the voltage is arriving at pins 4 & 5 through the LM3916. Does this mean it is faulty?
One other experiment had interesting results. With the circuit wired normally, If I run pin 4 straight to ground, the level meter works, sort of... the 10th Led never shines and the first 3 are always on. (I think this is because there is still voltage arriving at pin 5 through the LM3916, but most of it is being drained to ground through R4.)
My understanding of circuits is very basic. I would love to know if this LM3916 is faulty so I can order a replacement. What do you guys think?
