Arduino Tutorial 38: Using a Tilt Switch Cut Off With a DC Motor

Tilt Cut Off Switch
DC Motor circuit with a tilt switch cutoff

In this lesson we explore how to add a tilt cutoff to our DC motor project. In many cases, you may want to automatically turn your motors off in the case where your project or robot tips over. The tilt switch is a simple way to do this. The video below takes you through the process step-by-step.


If you need help hooking the circuit up, the diagram below shows you a schematic of what we are working with. All these components are part of our ELEGOO Super Starter Kit.

In addition, you will need to add the tilt switch, as shown in the video.

Below is the code we used, with the tilt switch connected to pin 2 on the arduino.



Arduino Tutorial 36: Understanding How to Use Tilt Switches in Your Projects

Tilt Sensor
This Circuit Gives Visual Indicator if Board Has Been Tilted

This is a simple project that allows you to create a circuit which will give a visual indication if the breadboard has been tilted. In the upright position, the Green LED is illuminated. To the left of the board is a tilt switch. If the project is tilted, the switch will go from the closed to the open condition. This can be detected on the arduino, and then the red LED is illuminated. The video below explains how to do this simple project.

You can get the kit we are using in these lessons HERE. You should create your own code based on the instructions in the video, but if you are having trouble, I include the code developed in the video below:
