How Measure Tilt Angle using SCA60C angle sensor and take action based on Angle

Using this Arduino code and SCA60C title angle sensor we can measure the angle of robotic arm or element. this Code is a vriation of the main code here where you can use this to take action for example turn ON or OFF something or do something when agale is equal, less or greator than some value.

Turning ON or OFF a buzzer or relay at certain angle

We define a pin of arduino as OUTPUT where relay or buzzer is connected. we call that pin controPin and have a vairable for desired angle where we take action at. We call it myAnle which holds the angle. We can have a time when the Arduino takes acction to turn ON or OFF the buzzer or relay, we can keep it in that state for certain time and we callit it waitTime. The wait time is millisecond. For 3 seconds we enter 3000 for example. If we don't want any delay, then we enter zero.
