After about 2-3 times of the loop running, the code goes to "abort" despite not pressing the button. Any idea why? enum DIR_ENUM { DIR_UP = 0, // Black DIR_DN, // Blue DIR_LT, // Yellow DIR_RT, // Green DIR_CNT }; const int buttonPin = 3; // the number of the pushbutton pi…

Sorry. I am new to this. Please bare with me. I really appreciate it. I've just now set my breadboard up just like this. It's still doing the same thing. [Screen Shot 2021-08-03 at 5.42.47 PM]

Your code said... const int buttonPin = 3; But you connected button to pin 2. [image] :roll_eyes:

[image] jj0932: Okay so you are saying no resistor is needed? No. INPUT_PULLUP supplies the required resistor, internally. Wire the button from PIN 3 to GROUND. Here are the options: [image]

Yes I recently just changed my whole layout and changed the code to pin 2. That's not the issue sorry I didnt mention that.

[image] anon94801460: No. INPUT_PULLUP supplies the required resistor, internally. Wire the button from PIN 3 to GROUND. And rewrite the IF conditional expression to LOW.

Ok changed the IF conditional expression to LOW. Not sure if this setup is correct. I'm sorry I am a VERY beginner at this. [IMG_8394]

[image] jj0932: Not sure if this setup is correct. No. You need to connect diagonally across the button.

Does someone mind drawing it out for me? I'm just not understanding, and I'm not understanding how to come up with the right setup. Thank you!

[pushbutton] Wire diagonally across the button leads at A and D or leads at B and C. You can't get it wrong and wire to two connected legs.

Code does IF statement even when IF statement isnt true?
