[android-developers] Re: Arduino vs Io-Io

The ioio is a controller board with USB host and a firmware designed to communication with android devices (the android devices work as usb devices in this case). I.e. the ioio is kind of a replacement for android accessory boards that works with android >= 1.6 (?) while android accessories need android >= 3.1(?).

Arduino boards typically have a usb device connector (this depends on the concrete arduino variant). As such, it can only communicate with USB host devices, i.e. not with all android devices. I'm also not aware of android software to communicate with arduino via USB.

So for an arduino solution, you need either an USB host shield (in that case, you would have to write something like the firmware oand the android lib of the ioio yourself) or bluetooth (see e.g. http://www.amarino-toolkit.net). The latency via bluetooth will be significantly higher than via usb, which may be problem depending on your application.

Normally, I would recommend to use the ioio. However, I don't know if your project has requirements that would change this recommendation.

You may ask further questions on the ioio user list https://groups.google.com/forum/?fromgroups#!forum/ioio-users. It seems more appropriate than this list. Ytai, the developer behind the ioio, is very active on that list and provides great support.

The ioio docu lives at https://github.com/ytai/ioio/wiki
