This project demonstrates how to create an anti-sleep alarm system for drivers using an Arduino Nano and a Relay Module. The system detects signs of drowsiness or fatigue in the driver and triggers an ...

The Arduino Nano, when paired with a relay module, allows control of high-power devices, enabling applications like home automation, industrial control, and robotics in various electronic projects.

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...

This project proposes the creation of a standalone alarm system based on an Arduino Nano board (ATmega328P) combined with a BK A7670E 4G GSM module. The system allows for remote activation and control ...

A relay is a device used to respond to an input signal and provide a connection between two or more devices. It can be used to control AC-powered devices, such as lights, fans, or other household ...

A relay module is an essential component in electronic systems that enables the control of high-power devices using low-power signals. It acts as an electrical switch, allowing a small current to ...

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, impacting the Arduino Nano RP2040 Connect, ...
