Bonezegei_HCSR04 is a simple and easy-to-use Arduino library for interfacing HCSR04 ultrasonic sensor module. The library provides functions for measuring distance, setting trigger and echo pins. The ...

This project demonstrates a low-cost intelligent traffic signal system using Arduino and ultrasonic sensors to reduce congestion caused by fixed-timer traffic lights. Four HC-SR04 sensors detect ...

lly decreasing, but historically, the barrier for developing hardware solutions has remained high. You usually need money, shipping time, and specific parts. However, that is changing. Today, I’m ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

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 ...

Once the program is running in the robot, you can go to your phone to find the GalaxyRVR SSID defined in the program. Connect to it with the password in the program, in our case: 12345678. Now find ...

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 ...
