Experimenting with Arduino and Ultrasonic-radar

With an Arduino and some inexpensive sensors you can experiment with and possibly recreate all manner of complex devices. One example of this is to build a simple "radar" style device, and this has been demosntrated by Ujash Patel with great success. By using an inexpensive ultrasonic distance sensor mounted on a servo, it can be rotated over the range of the servo and a distance taken for each degree.

This data can then be sent to a PC to be mapped graphically on the screen, and Ujash has used Processing to do this quite well - a screen that wouldn't look out of place in a movie or elderly submarine can be created to display the data from the sensor, for example:

This could be a lot of fun, and an interesting framework for adding "vision" to an autonomous robot. For complete details on this example, visit Ujash's Instructable page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.
