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 ...

A complete IoT solution for controlling an 8-channel relay module using an Arduino Uno, integrated with a Telegram bot for remote control.

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

This article will explore the workings of a relay module and provide a detailed guide on how to interface a single channel relay module with an Arduino.

In this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control ...

Smartphone-Controlled Arduino Projects: Use Bluetooth and Wi-Fi for Wireless Communication These two practical Arduino projects show you how to control a relay from a smartphone using an Arduino Uno ...

In order to use the ESP-01 Wi-Fi relay module, a programmer/programming adapter is required to program the ESP-01 module (see below). Also it is pretty easy to make your own programmer, or you can ...
