My circuit is exactly like this one:
View attachment 64366
I connected the 9v battery and nothing turns on, even when I tune the potentiometers. I noticed that all LEDs turn on when i remove the potentiometer connected to Pin 5, so that Pin 5 isn't connected to anything.
I have no idea what any of the pins 3 - 8 do.
Edit: I would like the range to be from 7 - 9 volts
