Once again Rui Santos has delivered with an interesting and useful Arduino tutorial. In this instalment he describes how to control simple DC motors that are connected to an Arduino via Bluetooth. The DC motors are controlled via an L293D driver IC, and the Arduino receives serial commands via an inexpensive Bluetooth module. For control purposes, Rui uses a simple Android app created with the MIT App Inventor - a free and easy way to write your own smartphone apps. In the following video Rui takes us through his project:
Even if you're not interested in controlling motors, the tutorial gives you the framework to generate your own remote-control systems from mobile phones or other devices with serial-capable Bluetooth. To get started, visit Rui's tutorial website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking into starting with Arduino and motor control, such as controlling a stepper motor (or DC motors) from your Arduino or compatible, check out our new 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.
