Creating a "knock lock" system

There's a few projects out there that can listen to a pattern of knocks and take action on the results, and the following example by Michele Marolla is a simple and easy to understand version. Using a piezo sensor to detect the knocks, the system can be taught new patterns to remember, control a servo (or other device) if the correct pattern is entered - and also play back the sequence to ensure the creator understands what needs to be done in the future. The project is demonstrated in the following video:

Although only a bare version, it's all there so you can fit the parts to your own enclosure. To find out more, visit Michele's project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

Have you been reading about Arduino and the types of projects created, but not sure where to start? Then order one our Experimenter's Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. 

However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects! So to get started or for more information and to order, check out the product page.
