This project uses a servo motor and ultrasonic sensor to continuously scan surroundings. It detects movement by measuring distance changes and triggers an alarm with a buzzer if significant variations ...

This project uses an Ultrasonic Distance Sensor to measure the distance in front of the device. Based on the distance, it controls four DC motors and a servo motor to steer and rotate the device: 🚗 ...

As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen run by a Raspberry Pi. If an object is detected in the 180-degree field of view of the sweeping sensor, a ...

Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...

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 ...
