Once again Rui Santos brings us another simple yet useful Arduino tutorial. In his latest instalment he demonstrates how to control an Arduino using text commands over serial via Bluetooth. A lot of people consider this to be difficult, however with the freely-available "Blueterm" Android app you can send and receive text - which an Arduino can easily receive and act upon. For the demonstration Rui controls a DC motor with an L293D motor controller IC which is useful in itself, for example:

When prototyping more advanced Arduino-based projects, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega range, we offer a complete range for you to work with.
