This repository contains the code and documentation for building a simple ultrasonic radar sweeper using Arduino. The device is equipped with an SG90 Micro-servo motor and an Ultrasonic Sensor (HC-SR04). The radar sweeps in front of it, and a beep is triggered every time an obstacle is detected.
-
Arduino UNO:
- The brain of the project, responsible for running the code and controlling the servo motor.
-
SG90 Micro-servo Motor:
- The motor that sweeps the ultrasonic sensor horizontally, creating a radar-like motion.
-
Ultrasonic Sensor - HC-SR04:
- Detects the distance of obstacles in front of the radar.
Connect the components as follows:
- Connect the servo motor to the designated servo pins on the Arduino.
- Connect the VCC, GND, Trig, and Echo pins of the ultrasonic sensor to the Arduino.
-
Clone this repository:
git clone https://github.com/smazurs/Ultrasonic-radar-sweep
-
Open the Arduino IDE and upload the
ultrasonic_radar_sweep.inosketch to your Arduino UNO. -
Power up your Arduino and observe the radar sweeper in action.
The ultrasonic radar sweeper will start scanning in front of it horizontally. If it detects an obstacle within a specified distance, a beep will be triggered, indicating the presence of an object.
You can customize the following parameters in the code to suit your preferences:
-
Sweep Range: Adjust the range of the servo sweep in the code by modifying the pos constants: (pos = 0; pos <= 180; pos += 1)
-
Detection Distance: Set the distance at which the ultrasonic sensor triggers a beep by modifying the (distance <= 10) constant.
-
Beep Frequency Set the beep frequency by modifying the (buzzer, 500) constant.
