Description:
Operation principle of this DIY Arduino Mini Radar: The ultrasonic module will send out ultrasonic waves, and calculate the distance of the object in front by calculating the time length of receiving the echo. The servo can be positioned at any angle from 0 to 180°, and the servo is equipped with an ultrasonic module to detect the distance of objects within 180° around it. The measurement results are output through the display screen and presented graphically. It is a very interesting and educational Arduino board application project.
