If you do not know about LED and ultrasonic sensor (pinout, how it works, how to program ..), learn about them in the following tutorials: -Arduino-LED tutorial ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

This project demonstrates how to use an HC-SR04 ultrasonic sensor with Arduino and ESP32 to measure distances accurately and integrate them into DIY electronics or IoT projects. The ultrasonic sensor ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...
