This project is a simple automatic toll gate system built using Arduino, an ultrasonic sensor, a servo motor, and a 16x2 LCD display. The system detects when a vehicle approaches the gate, opens the ...
Abstract: Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper ...
A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...
In this tutorial, you will learn how to send WhatsApp messages directly from an Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex ...
Hello Hackers! Today we have a really interesting topic. Searching the internet, I didn't find any simple solution on "How to read data from car parking sensors," so I decided to write a short and ...
Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Arduino heart rate monitor using Pro Mini PulseSensor and OLED for beginners
In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module
Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...
Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...
Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
