The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the ...

Application to Ultrasonic Sensors and Systems Abstract: This work presents in detail a new method for the optimization of rectangular spread spectrum excitation signals for its use in simple and ...

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...
