Be it the long stretched highways or your doctors front door, we have sign boards placed everywhere to provide us information. But these sign boards are often boring and cannot be configured as per our interest from time to time. So in this project we are going to build a Bluetooth controlled Sign board using an 8*8 Matrix display. A unique feature of this project is its android application which allows the user to control all the 64 LEDs individually from the mobile phone.

In this tutorial let us learn How to interface HC-05 Bluetooth Module with AVR ATmega8 microcontroller. We will establish communication between Android mobile and Atmega8 through Bluetooth module which takes place through UART serial communication protocol. In this project we will control a LED using Bluetooth of our smartphone. 

Controlling LEDs with voice command seems to be a difficult task, but it’s easy and you can quickly build it. We just need an Arduino UNO to serially communicate with HC-06 Bluetooth module and a smartphone to send voice command to Bluetooth module HC-06. For receiving voice command we are using “Arduino Bluetooth Voice Controller” android app which you can download from play store (link is given below). 


Using a Servo motor is common in Robotics for precise control. Here, in this tutorial we are going to show you how to use a Servo motor wirelessly with an Arduino UNO and an Android device via Bluetooth connection. We already controlled servo with Arduino, this time we are controlling Servo wirelessly using Bluetooth Module HC-06.


In this project we are going to build an Android Phone controlled robot using 8051 microcontrollers and Bluetooth module. The robot is designed using DC motors and the direction of DC motors will be controlled by the commands received from the android application. The status of the robot is sent back to the Android app. This project will also help for interfacing of HC-05 Bluetooth module with 8051 microcontrollers.

Raspberry Pi is very popular for IoT projects because of its seamless ability of wireless communication over the internet. Raspberry Pi 3 has inbuilt Wi-Fi and Bluetooth, and Bluetooth is a very popular wireless communication Protocol. Today we going to build a Remote Controlled Car using Raspberry Pi 3 and Bluetooth, here we will use Smart Phone as a remote to control the car.

In today’s modern world, where ever we go we have lots of electronic devices around us. But, out of all, there is only one device that we personally have in our pockets all the time. Yes, it is our mobile phones. Now Mobile phones have become more than a device used for communication, they are our cameras, they are our maps, they are our shopping karts and what not?

Raspberry Pi is very popular for IoT projects because of its seamless ability of wireless communication over internet. Raspberry Pi 3 has inbuilt Wi-Fi and Bluetooth, and Bluetooth is a very popular wireless communication Protocol. So today we are going to Control Home Appliances through Smart Phone using Raspberry Pi 3 and Bluetooth.

Ever wanted to build a Face Tracking Robotic Arm or Robot by simply using Arduino and not any other programming like OpenCV, visual basics C# etc? Then read along, in this project we are going to implement face detection by blending in the power of Arduino and Android. In this project, the mobile camera will move along with your face with the help of servos.

In this project we make a Cool Speedometer for bikes or any automotives by using Arduino which broadcast the speed using Bluetooth to an Android application that we created using Processing. The complete project is powered by an 18650 Lithium cell and hence highly portable along with your vehicle. To spice it up a bit more I have added the option of charging your mobile phone as it displays your speed. Yes, you can also use this as a power bank for your mobiles on the go as the 18650 has high charge density and can easily be charged and discharged.
