Hi, im trying to code a button to control a servo motor but I'm running into the issue that I'm needing to hold down the button to stop the servo motor from rotating rather than having it so if I press it once, it registers that the button state is HIGH and stops the motor without having to hold it down.
Have a look at the state change detection tutorial.. It shows how to detect the state transitions as opposed to the state levels.

While you're doing this:

... change things to the better practice of press meaning low. Wire the button to ground from the pin, pinMode to enable internal pullups, and change the code to look for a low.

Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thanks.. Tom..
