I am working on assignment 4a, at step 2 you have to control your circuit by running the program. When I do this, my leds go on one by one. Then they stop at the same time. But if I push a button, the led next to it doesn't light up. I checked my wires again but can't find a mistake. How can I fix this?
Large chance the wiring or placement of the buttons is incorrect. Take a close look at the detailed photo of the buttons in the assignment. Did you maybe orient them 90 degrees turned?
