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 relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

This is a simple Home Automation project using the DIY micro-controller (Arduino), Bluetooth Wireless Module and Relay. This setup can be used to ... Instead of Arduino Nano R3.x used here, you can ...

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 code sets the variable "relay_pin" to 7, which means that the relay is connected to digital pin 7 on the Arduino Uno. void setup() { pinMode(relay_pin,OUTPUT); } In the setup() function, the ...

In this tutorial, we are going to interface RDM6300 RFID Reader Module with Arduino Nano. The RDM6300 RFID Reader is one type of RFID module with a 125 kHz frequency. This RFID module can read data ...

The intention was to make a universal feeder relay module that could be used to control a regular ... Although the initial setup is centered on an Arduino Nano (Seeeduino Nano in my case), a better ...

If you want to build something yourself for less, you can get an Arduino Nano RP2040 Connect with a Raspberry Pi ... You could also use a relay module to act as a switch that would turn on a light ...

the Arduino Nano RP2040 Connect, integrating the RP2040 microcontroller developed by Raspberry Pi Foundation with the u-blox NINA-W102 Wi-Fi and Bluetooth radio module, as well as a rich set of ...
