(had a problem with my laptop where it did not execute code [problem with breadboard, nano IOT 33 was not installed]. tried to use microstudio’s computers- code was working properly but did not how to access serial monitor.)
CORRECTION: arduino program did not install properly. Had to reinstall it for it to be able to execute code correctly.
I followed the diagram for the initial setup.
(Q: Was not completely sure why the resistor was required for the button? Not sure of its function.)
Circuit initially wasn’t working.
And my input+output code was initially incorrect. (Accidentally coded for all input.)
void **setup**() {
pinMode(2, **INPUT**);
pinMode(3, INPUT);
pinMode(4, INPUT);
}
[This was all Input rather than output]
My wires were also in the incorrect place for input/output. I switched them around so it was correct.
