In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

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 ...

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 ...

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, ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source ...

In recent years, the demand for smart security and automated monitoring systems has increased significantly due to growing safety concerns and the need for real-time surveillance. Traditional security ...

Abstract: This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable ...

Welcome to the Visual Studio Code extension for Arduino preview! The Arduino extension makes it easy to develop, build, and deploy your Arduino sketches in Visual Studio Code, with a rich set of ...

Abstract: This paper introduces an Arduino-based color-sorting conveyor belt system that automates object sorting by color. Employing a TCS3200 color sensor, an Arduino microcontroller detects red, ...
