What is the pushButton for?

this is to break the while loop when it is pressed.

@gygonzales

And when you said connect another button, do you mean aside from the SENSOR_PIN_13 that I already have?

yes, another push button which is used to break the loop.

@gygonzales

Isn’t the while (digitalRead(pushButton)) the same as while (true)?

How is it same?

Hi Shramik.

This portion of the code that you gave:

while (digitalRead(pushButton))

does this mean when the button is pushed it goes inside the loop statement and goes outside the loop when the button is released? Can it be more explicit like this?

while (digitalRead(pushButton == 1))

@gygonzales

yup you are almost right but should be opposite as the button is pulled up. so it is 1 when not pressed and it remains in the loop and when pressed it is 0 and exits the loop.

@gygonzales

while (digitalRead(pushButton == 1))

should be: while (digitalRead(pushButton) == 1)
