Circuit 13

I attempted circuit 13 as homework. I say "attempted" because it did not work like it was supposed to. All that I was able to achieve was one LED lighting up but not turning off or switching to the next LED. I attempted to trouble shoot the problem I:

1.) disconnected and reconnected the circuit at least 3 times.

2.) I tested both LED's to make sure one of them wasn't burned out or malfunctioning

3.) I tried two different transistors

4.) I tried two diodes as well two relays both achieved the same results.

5.) I double checked the code but it was example code that was used and every time it verified successfully..
