If you've been experimenting with the new Beaglebone Black or the original and would like to interface them with an Arduino board, don't panic as the solution is quite simple. Written by Instructables user "chrwei", they've explained how to use a python toolkit to send and receive serial data to the Arduino via a level-shifter board. Although the Beaglebone is much more powerful than an Arduino, it lacks the wide variety of robust hardware interfaces, so having an Arduino to do that kind of work is a solid choice.
If you're going to interface your Beaglebone or other 3.3V development board with an Arduino or other 5V system - you'll need to interface the GPIO pins with different voltages. When you're faced with this situation - don't panic! Make sure you have some of our LEVEL: bidirectional 5V-3.3V level converters in stock. For more information and to order, click here.
