Sonar with Arduino and Processing

This is a small sonar made with Arduino and Processing.
It is an ideal educational project to combine design and programming.
The structure of the Sonar is made of two components:
- A servo holder
- An ultrasonic holder
- A wooden base of about 120 x 70 mm
the two components were printed on a Geeetech printer.

The circuit board is made using:
- Board Arduino One
- A SG 90 servant https://www.amazon.it/Longruner-servomotore-elicottero-aeroplano-LKY66-UK-5/dp/B07236KYVC/ref=sr_1_1_sspa?adgrpid=51580092134&gclid=CjwKCAiAlO7uBRANEiwA_vXQ-7AhpFDXSW1zaXPbnYQiPBVEvBQQcJO_A9JiXEEUj3s4S6wsVpjr1xoC7x4QAvD_BwE&hvadid=255185375029&hvdev=c&hvlocphy=1008883&hvnetw=g&hvpos=1t1&hvqmt=e&hvrand=5018447069551233651&hvtargid=kwd-318145120239&hydadcr=4796_1745387&keywords=servomotore+arduino&qid=1574680126&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUE0MlJRNFYyRUxTWEsmZW5jcnlwdGVkSWQ9QTA2OTY5OTYxSFdDNzRYUVIyT05LJmVuY3J5cHRlZEFkSWQ9QTA0MzE5NDIzOUhBQlBBWUNGT0tKJndpZGdldE5hbWU9c3BfYXRmJ
