You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Vehicle Detection: Ultrasonic sensors monitor each parking slot and send data to the Arduino Uno. Slot Availability Display: Real-time updates shown on an LCD using I2C communication. Barrier Control: ...

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal ...

The Arduino UNO R4, released in two versions last year, supports the CAN bus in terms of hardware and software. In this article we look at some handy CAN modules, an experimental setup, and the basics ...

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 ...
