Lesson 11: Using Tilt Sensor Switch with Arduino

If you don't like to see ads while video is being played you can purchase this course for $200 from Udemy or purchase YouTube premium Here

Tilt switch or sensor is sensor when it is leaned to from a certain position, it establishes contact bewtween two pin. We detect the conect using Arduino and take action to do something.

A tilt sensor can be installed on a robotic arm and when the arm moves to certain position we either turn ON something or turn OFF .


 /*
 * S02-01 Tilt
 * This is the Arduino code for tilt switch to
 * turn a relay ON which the relay
 * can turn a light or alarm ON
* tilt switch is connected to pin 2
 * Relay is connected to pin 8
