I'm having a weird problem, I made a circuit to turn off the LEDs in my clock for 30 mins. The timer works fine but to turn off the LEDs I need to connect two pins on the 7-segment display set. When I connect them directly the LEDs will turn off. But when I connect one side to a transistor and the other side to the other side of a transistor and give the base power, they still act like they're not connected.
At first I thought that the transistor had too much resistance but eventually eliminated that.
I wrote a long post deeply describing the situation but I felt like it would make things more confusing.
If you need more info I can post it.
Attached is the diagram. I know I that I did a triple inverter but I did it because it made it less confusing for me.
I'm thinking that there's something about transistors that I don't fully understand that is causing my problem.
Thanks for any suggestions.
