Hi! Need help I want to create a passcode(buttons/switches) like program in which on typing the passcode the arduino will perform the program. But in case I press a wrong button/switch/digit I should be able to restart the program. Or is there any other way to clear the wrong pressed button/switch/digit.
And in general I would appreciate if someone would be able to tell me how to control the reset or restart(that is what I call it) switch/button. in the sketch/program.
