This project uses an HC-SR04 ultrasonic sensor to measure the distance of an object. If an object is detected within a specific range (e.g., 10 cm), the SG90 servo motor rotates to 90 degrees, the ...

This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...

The project includes two components connected to the Arduino UNO board. The bucket is made of cardboard. And on it we have a lid that needs to be opened when approaching the object. The task of ...
