Android Phone Used As a GSM Shield for Arduino




Here my another video showing how to use app inventor and bluetooth communication to interface an arduino board and an android device. This time I am showing how to use the texting function in order to turn the phone into a free GSM shield for arduino.

If you want more general information on interfacing the two, setting it up and want to see more examples - check my earlier instructable ->
Wiring and code is the same as in that example the only difference is the app.

The app can be downloaded here ->

The source file (allows you to easily modify the app) ->

    yes, that's precisely how you can use it - you can both receive and send text messages as well as make phone calls
