The ultrasonic sensor acts as the input and the servo motor acts as the output, the Arduino UNO microcontroller is the main brain behind the project. The block diagram for Arduino smart dustbin is ...

When the object comes within the range of the ultrasonic sensor the ... and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital I/O pin on the Arduino Board.

This project uses an HC-SR04 ultrasonic sensor and Arduino UNO to measure the distance of objects in both centimeters and inches. The measured data is displayed on an I2C LCD. The project was ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with ... a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a ...

In the following diagram the connection can be observed. Things to keep in mind: The resistors are 220 Ω and are placed in series with the LEDs. The Arduino ultrasonic sensor connects to two digital ...

Abstract: 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 ...
