So, here's the issue. I'm a bit new to coding and I'm not quite sure what I'm doing wrong. I already verified that all of the parts are working correctly, and I can get the motor to work both ways with separate pieces of code. In short, I'm trying to press the sensor once and have the motor turn clockwise for a set period of time and have the LED turn on when it is complete. When I press the sensor again, I want the motor to turn counterclockwise for the same set of time and the LED to turn off when it is complete. Right now,
I press the sensor and nothing happens besides the sensor lighting up green. Any tips would be greatly appreciated! Here's what I'm working with.
Here's what I have for code so far.
