Hi, I need some help figuring out how to have the sound stop after the distance is no longer greater than 300. Right now once it gets to while(x>300) { tone(8,500); } noTone(8); Heres the full code: int x; //const int switchPin = 2; const int motorPin = 9; //int switchState =0; …

How to run a loop only once while having constant update on a sensor?
