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 ...

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 ...

The code for this project is written in the Arduino programming language (based on C/C++). It uses the digitalWrite() function to control the state of the LEDs connected to the Arduino pins. The ...

This project uses an ultrasonic sensor to measure distances in centimeters and controls a set of LEDs based on those distances. The project is designed for Arduino boards, and you can use it to build ...

[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ ...

The word LiDAR, the ‘Li’ meaning ‘light’ indicates a device for optoelectronic echolocation. Instead of radio frequencies, the Lidar transmits a pulsed laser beam, the echo of which allows the ...

If you’ve made a robot or played around with electronics before, you might have used a time-of-flight laser distance sensor before. More modern ones detect not just the first reflection, but analyze ...

Makers and electronic enthusiasts searching for a small laser sensor may be interested in a new Indiegogo crowdfunding campaign which currently has 19 days left to run and is raising money to take the ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
