Hi everyone, I'm new to arduino and programming and general and am looking to make a project that allows me to make a 4 digit combination. I'm just using an arduino board and an LCD screen. I'm just having trouble figuring out how to store the four digits in arrays. for example, if SWITCH_1 was pressed 4 times it would record 4 and I would later be able to access that later when I wanted to unlock the combination.
Any help is appreciated.
Thanks.
for example, if SWITCH_1 was pressed 4 times it would record 4
Counting the number of times a switch becomes pressed, or released, is trivial. That's what the state change detection example is all about.
I don't see, though, the relationship between switch 1 being pressed four times and the value in a combination.
Suppose that the combination was 1, 7, 4, 8. I would expect, then, to have to press switch 1, then switch 7, then switch 4, and then switch 8. I would not expect to have to press switch 3 four times.
Even if that was the expectation, there is nothing in your spec about having to press the switches in any particular order. As long as each switch is pressed the proper number of times, you'd be allowed in.
