Arduino based Mini radar Detection Hello friends in this video I have made a Mini compact Radar with display, for that I have used HC-SR04 ultrasonic sensor, this sensor emit ultrasonic sound which came back to sensor after reflecting from an object.
all the data visualization is displayed on 1.8″ ST7735 display, if any object detect by radar it’ll show in display in red line.
There is four main components of this project
Arduino nano is the braing of our project
HC-SR04 is ultrasonic sensor this sensor emit ultrasonic sound waves which human can’t listen , this sensor generate some value in proportion to the reflected ultrasonic sound waves from the object, on this we can also tell the distance of object from the sensor.
SG90 micro servo is used to rotate ultrasonic sensor in 180 deg
ST77535 display is our monitor to visualize all data on screen
Step 3: Circuit
