This project implements a home automation system using an Arduino and an 8-channel relay module. The system allows users to control various home appliances and devices remotely through a serial ...

This is a simple Home Automation project using the DIY micro-controller (Arduino), Bluetooth Wireless Module and Relay. This setup can be used to control the relay from Android mobile phones using the ...

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 ...

HC-05 Bluetooth Module. HC05 is basically a Bluetooth module which supports Serial Port Protocol (SPP) and is popularly used in many wireless applications. HC05 can be used to switch between master ...

I have made all the proper connection and uploaded program to Arduino Uno and connect relay module and bluetooth hc-05 to Arduino and my mobile.but i’m facing a problem as i turn ON 12v power supply ...

Default baud rate of new Bluetooth module is 9600 bps. You just need to connect rx and tx to controller or serial converter and give 5 volt dc regulated power supply to module. Bluetooth module has ...

The Bluetooth module wants 3.3v logic levels so that is taken into account. The image above shows a buffer chip doing the conversion, but the Fritzing schematic on the post uses a voltage divider.

An Arduino mini pro provides the brains. ... If you need help reprogramming the HC-05 Bluetooth module, ... but I’ve mostly been using the USB battery pack with the relay. Report comment. Reply.
