Control DC motors from an Android device with Arduino and Bluetooth

Once again Rui Santos describes what seems to be a complex topic in simple terms, and in this example he shows us how to control DC motors from an Android device via Bluetooth.

An Arduino or compatible board with a DC motor and control circuit or shield is also fitted with a serial Bluetooth device, which receives commands from an Android app that's created with the free MIT App Inventor. This also gives the maker freedom in designing the user-interface on the Android app thanks to the easy coding. Rui gives us a demonstration in the following video:

The commands from the Android device is in the form of simple serial text, and the Arduino could also send feedback data back for a more interactive experience. However for an easy start check out Rui's website. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well.

 There's so much you can do with an Arduino and motors - and the base of any project is a solid motor shield - such as our HBRIDGE: DC/stepper motor shield. Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners' guide and documentation - motor control couldn't be any easier. For more information and to order, visit the HBRIDGE: page.
