Hi Thanks for your help, My code:
Note: The TM1637 Display isn’t connected anymore.
Everything works fine, but instead of “checking” the sequence after 7 inputs I want to check the sequence every time a button is pressed. So after a button on the keypad is pressed, the Arduino checks if the last 7 buttons == code
