Sonar with Arduino and Processing

thingiverse

This is a compact sonar made with Arduino and Processing. It's an excellent educational project for combining design and programming expertise. The structure of the Sonar consists of two main components: A servo holder, an ultrasonic holder, and a wooden base measuring about 120 x 70 mm. Both components were printed using a Geeetech printer. The circuit board is constructed with: An Arduino Uno board, a SG 90 servomotor (available at https://amzn.to/37CAvgk), an HC-SR 04 ultrasonic sensor (available at https://amzn.to/2qHNjBn), and a breadboard. Other tools used include: A hot glue gun, screws, and a screwdriver. To display the sonar's readings, follow these steps: Open the Arduino sketch called Arduino_radar (located inside the Things File); check the COM port; open the Processing sketch called sonar_con_processing_ink (also located inside the Things File). Important: If the program doesn't work, ensure that you've changed the value of the COM port to match the one in the Arduino sketch (indicated by a red rectangle in the image). If Processing encounters an error related to font loading (denoted by a blue rectangle), follow these steps: Open the tool from within Processing; click on 'create font'; insert the correct OCRAExtended font in the window that appears. To adjust the screen resolution size, modify the size values indicated by a green rectangle. Enjoy!
