Simple experiment with Bluetooth and Arduino

14201

This is one of the simplest and easiest experiments using Bluetooth adapter, Android and Arduino.

You just need an Android serial emulator, any type of emulator should work for this experiment. I recommend Blue term , you can find this application on your Android Market (Google Play).

In this experiment, as soon as you connect your phone to Arduino via Bluetooth, you will see numbers increasing from 0,1,2 and so on. While counting, if you enter a text or number on your phone, for example, ‘abc’ , you will get a message “Arduino received: abc” on your phone screen.

This experiment makes the use of a general and low cost Bluetooth adapter available on buildcircuit.net

 Connection between Arduino and Bluetooth Adapter:

GND- GND

5V- 5V

RX(Bluetooth) – TX (Arduino)

TX(Bluetooth) – RX(Arduino)

BuildCircuit has recently released a perfect DIY shield for Android-Arduino experiments. Just stack this Bluetooth adapter over the shield and do several experiments using Amarino and Bluetooth serial emulators. Check out the shield.
