Abstract: This paper describes an LPG gas alarm and auto shut-off prototype built around an Arduino Uno to make homes and factories safer. At its core sits an MQ-2 sensor that tracks gas levels ...

Connect a >1M OHM resistor between ADC1_0 (GPIO 36) and GND. Put a flying cable in GPIO 36. Now connect to WiFI "ESP32-EMF" and enjoy.

This project demonstrates real-time object detection using Edge Impulse models and a Flask web interface. Designed for Arduino App Lab and used for the MWC Barcelona 2026 workshops.

Abstract: A novel back EMF detection method for sensorless BLDC motor drives without the motor neutral point voltage information is presented in this paper. The true phase back EMF signal can be ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...

Figures of merit for single-photon detectors. The most widely quoted figure of merit for photodetectors is the noise equivalent power (NEP)24, and this has proved useful for optical power measurements ...
