Mini Radar Ultrasonic Radar Maker Open Source Arduino Project Tft Lcd Screen Detection Robot
Operation principle: The ultrasonic module can send out ultrasonic waves, and the distance of the object in front of it can be obtained by calculating the length of the received echo. The steering gear can be positioned at any angle within 0~180°. The steering gear is equipped with an ultrasonic module to detect the distance of objects within 180 degrees. The measurement results are output through the display and presented graphically. A small set of interesting Arduino projects.
Effective detection distance: 10-300cm
