radar project

1. Radar Project Components

• 1 × Arduino Uno

• 1 × Servo Motor

• 1 × Ultrasonic Sensor (HC-SR04)

• Jumper Wires

• Breadboard

• USB Cable for Arduino

First I connected the Ultrasonic sensor with the Arduino Board in the following way:-

VCC -5V

GND-GND PIN

TRIG -2

ECHO-3

Then next I connected the servo motor as follows:-

RED wire - 5V

BROWN wire- GND

ORANGE - 4

Here, I encountered a problem where the servo motor unfortunately refused to rotate. I suspect there is an internal mechanical issue with the servo, as I tried connecting it directly to a 5V supply, but it still did not work. It only produced a very faint sound that was barely audible.
