How To Make Radar With Arduino UNO Using Ultrasonic Sensor

  Creating a radar system with an Arduino UNO and an ultrasonic sensor involves a few straight forward steps. First, you'll need to connect the ultrasonic sensor's trigger pin to one of the Arduino’s digital output pins and the echo pin to a digital input pin. Then, write a simple Arduino sketch to send a pulse from the trigger pin and measure the duration of the pulse received on the echo pin. This duration, proportional to the distance of an object from the sensor, can be calculated using the speed of sound. By continuously taking readings and mapping them to distances, you can plot these measurements to visualize objects in your environment, effectively creating a basic radar system. To display the results, you could use a serial monitor or even integrate an LCD display for real-time feedback. Here is the code below ,- //radar.ino #include <Servo.h>  const int trigPin = 9; const int echoPin = 8; long duration; int distance; Servo myServo;  void setup() {   p...
