![]() Sets the trigPin on HIGH state for 10 micro secondsĭuration = pulseIn(echoPin, HIGH) // Reads the echoPin, returns the sound wave travel time in microseconds Function for calculating the distance measured by the Ultrasonic sensor rotates the servo motor from 15 to 165 degrees MyServo.attach(3) // Defines on which pin is the servo motor attached PinMode(echoPin, INPUT) // Sets the echoPin as an Input PinMode(trigPin, OUTPUT) // Sets the trigPin as an Output Servo myServo // Creates a servo object for controlling the servo motor Variables for the duration and the distance ![]() Defines Tirg and Echo pins of the Ultrasonic Sensor Radar using ultrasonic sensor works in software makes the reaction according to the waves received.Īrduino code for ultrasonic radar:- // ultrasonic sensor work as an object detector in this project. at that time the graph interface inside the software becomes red in the object area. and if any object comes under the range of the ultrasonic sensor it starts to detect the object. and the whole time a graph interface make in the simulation software. The ultrasonic sensor rotates with the servo motor and transmitted the ultrasonic waves during this time. the interface of this software is pretty the same as the Radar interface. it consists ultrasonic sensor mounted over the servo motor and connected to software that shows the output on the computer screen. so, this is called radar and it works on the Ultrasonic frequency. ![]() It is just like mini radar it recognizes the object in the path and makes a red affected area near the object. As I mentioned in the above paragraph the Arduino Radar detector project is popular nowadays and now we will understand what actually is it.
