ICM HW3 Color Change Logic Working

//all the boolean values started as false at the beginning of the sketch
//if slider reaches the area after the stop angle
if (angle > stopAngle || angle < 0) {
	//reset arc rotation
	angle = 0;
	//define when to change color
	//if hasn't passed the stop angle before
	if (!passedStop) {
		//flip boolean value
		changeCol = !changeCol;
		passedStop = !passedStop;
	}
} else {
	passedStop = false;
}
//change color
if (changeCol) {
	h += 20;
	//reset after changing color
	passedStop = false;
}
