In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can ...

The following article shows you how to interface the SR04T Waterproof Ultrasonic sensor with an Arduino Uno to obtain distance data. The article also discusses the working of the module along with a ...

Set up the Arduino Uno board for programming and control. Motors: Connect the two motors to pins 2-5 for motor control. Ultrasonic Sensor: Wire the ultrasonic sensor to pins 6 (trigger) and 7 (echo) ...

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 ...

This research comprises an ultrasonic sensor module, an Arduino Uno microcontroller, and a visual display, such as an LCD or LEDs. The ultrasonic sensor emits high-frequency sound waves and measures ...
