This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

The system is built upon four foundational pillars: Autonomous Safety: Utilizing MQ-series gas sensors and flame detectors to provide real-time protection against fire and gas leaks through automated ...

ROME, ITALY - DECEMBER 6: A torchbearer shares the torch flame to Italian singer Achille Lauro carrie the 2026 Milan Cortina Winter Olympics torch in front of the Colosseum during the Torch Relay to ...

With the ESP32-P4 not having any wireless functionality and instead focusing on being a small SoC, it makes sense to combine it with a second chip that handles features like WiFi and Bluetooth.

Smart home systems are a new design development that has been started to be developed recently and is expected to spread widely in the future. In addition, smart home systems can not only turn devices ...

Abstract: Arduino boards are very useful for teaching electronics and programming in vocational training, but their massive use can discourage the learning of hardware development techniques by ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

The MT6701 is an easy to program magnetic rotary position sensor with a high-resolution 12-bit analog, PWM, UVW, ABZ. With SPI and I2C output is 14 bit. They should provide magnetic button ...

Abstract: In this paper, we study covert communication in a multi-antenna two-way relay system, where two source nodes exchange their messages through a relay. Then, the relay tries to disseminate ...
