I'm trying to connect Arduino Leonardo to an Android tablet. I would like to make the Arduino send commands (using pushbuttons or a slider for example) to the tablet to switch between pages, to select a file on the desktop, to scroll up and down the screen, etc.

Thanks. I will really appreciate your help.


Perhaps this is not exactly what you are looking for, but from your examples it seems like using navigational commands from the keayboard/mouse would accomplish a lot of what you are requesting.

Android has USB HID support from honecomb, so you should be able to create a sketch to emulate a keyboard and mouse based on the IO data and it should work with your android device just by plugging the USB cable (if emulating a mouse, it will display the mouse cursor as soon as it is connected).


First, get a Lightblue Bean, http://punchthrough.com/bean/

It has everything you need: - arduino - bluetooth - API - code example - android sdk - ...

Develop your product using this platform.

If you want to scale and build your own platform, then you will have a foundation to validate your work.

It is a good idea to use a LightBlue Bean, only if you are using the Android SDK! https://bitbucket.org/littlerobots/beanlib

You can read more about the SDK, and get advice from people who are actually using it. http://beantalk.punchthrough.com/t/announcing-unofficial-android-sdk/394
