This article is nothing but only the revision of previously published articles about sending data from Nokia N900 and Android Phone to Arduino. In this experiment, you will see numbers increasing on Serial Monitor of Arduino and same numbers will be seen on Android interface also.
If you have never done this kind of experiment, I recommend you to read these articles first:
Click on the given links so that you will know the required components and setups for doing this experiment.
a. Changing the baud rate: In this article you will know how to change the baud rate of bluesmirf module. It is very important to know the baud rate of Bluetooth module so that you can set the same rate on Arduino’s serial monitor also. Set the baud rate to 9600. You will get detailed description on the given link.
b. Sending data to arduino and seeing the data on LCD: In this experiment, you will send some data to arduino and you will see the same data(text) on LCD. It’s a very interesting experiment.
c. DOWNLOAD This arduino code.: Download this arduino code and write it to arduino chip.
Then follow these steps:
The circuit configuration is exactly same as the setup for this experiment: http://www.buildcircuit.com/bluetooth-communication-between-android-and-arduino-using-free-applications/
-Open the Serial Monitor of Arduino, you will see a sequence of numbers.
- Connect Bluetooth of your phone to Bluesmirf module.
- Then, you will immediately see the same numbers on Android Interface.
- When you send any text from the phone, you will immediately see the same text on arduino’s monitor also.
For example, if you send “hello”, then you will see “I received: hello” on arduino’s monitor also.
You don’t need LCD for this experiment.
You can see the detailed description of this experiment on the following video:
