I am creating a memory game with the Arduino. It has four buttons, each for a different colored led. The leds will blink in a random sequence and either fail or add another light in the next sequence if the user presses the correct buttons. I have also attached an lcd screen to late implement a score tally.
Right now, the welcome lights display and the sound is working fine, but when the sequence starts, it will act as though I am pressing a button and proceed through the fail light method. I think the last method is causing this issue where I am comparing the button pressed to the sequence.
I would appreciate any help!
