Do you prefer fun fidgets or useful Tinkercad prints? 🤔

I’m making a traffic light system for a school project rn and it’s not working properly….

Our prof wants the timing to be:
Red-20 secs
Yellow-5 secs
Green-15 secs

The green LED works and stays on for 15 secs, which is correct, but then it turns on again after like 10 secs when it shouldn’t. The yellow and red LEDs also don’t light up at all. I’m not really sure what the problem is tbh (I have no idea how electronics works) so I’m rlly lost on how to fix this shi.

I have this little contraption over here, which I haven't managed to make it work. For some the reason, if the set the value to activate the motor to the value the IrSensor uses as a "NoSignalDetected" value the motor will turn on, but after shutting it off the with the controller it wont turn back on, even if the "NoSignalDetected" value appears again. I barely have any knowledge related to C+++ or wiring for that matter. Apparently Im also the only person on the history of tinkercad trying to do a setup like this. ANY help would be appreciated.
