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 ...

It works in two different modes, Normally Open (NO) and Normally Closed (NC). in our project, we will use it in Normally Open mode which means when the relay is switched off the circuit will be broken ...

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

These two practical Arduino projects show you how to control a relay from a smartphone using an Arduino Uno either over Bluetooth or over Wi-Fi via an ESP8266 -based ESP-01 module. Whether you are ...

The input pin of the Relay module is connected to pin 7 of Arduino. Direction and Step pins of the A4988 module are connected to 2 and 4 pins of Arduino. In this project, an IR sensor is used as an ...

Arduino Uno is powered with a 12V DC adaptor/power source. The relay module and Bluetooth module can be, in turn, powered using a board power supply of Arduino Uno. Author’s prototype is shown in Fig.

We will use this Hall Effect mechanism to lock and unlock the door automatically. To learn more about Hall Sensor and its working, follow the link. Components Required Arduino Uno RFID-RC522 Module ...
