2.17 Tilt Switch

Overview

In this lesson, you will learn about tilt switch. Tilt switch can be used to detect whether objects tilt, which is of great value in practical applications. It can be used to judge the tilt of bridges, buildings, transmission line tower and so on, so it has an important guiding function in carrying out maintenance work.

Code

Note

  • You can open the file 2.17_tiltSwitch.ino under the path of sunfounder_vincent_kit_for_arduino\code\2.17_tiltSwitch directly.

  • Or copy this code into Arduino IDE.

After the codes are uploaded to the Mega2560 board, you can open the serial monitor to see the readings of pins, which displays 「1」 or 「0」 when Tilt Switch is vertical (bringing the internal metal ball into contacting with the Wire Pins) or tilted. For detailed explanation of codes, you can turn to 1.4 Digital Read.
