With an Arduino you can build and replicate or emulate a wide variety of devices, and one example of this has been demosntrated by Jan Muller with his home-made sonar device. It used an Arduino to control a servo or motor with an ultrasonic distance sensor attached. The distance and rotational position data is fed from the Arduino back to a PC running a processing app which can interpreter the data and create a retro radar/sonar style display, for example:
Although quite simple, it could be used for fun - and also more practical projects such as object-avoiding robots and so on. The code can be found here, and visit Google+ for more discussion. 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!
