Introduction: Ultra Sonar

About: 4D Makers is a group of curious engineers and enthusiasts who finds great satisfaction in creating and building anything from electronics.

This project named Ultrasonar used gen4-uLCD-50DT-AR resistive touch display as a display. A visual representation of the data gathered by the ultrasonic sensor with a servo motor will displayed on the display’s screen. This project is a miniature of a simple sonar systems and as well as a good starts if you are planning to build your own simple radar systems.

Step 1: Build


  • gen4-uLCD-50DT
  • gen4-PA
  • Arduino Adaptor
