Planet Arduino

Have a significant other that isn’t the best at picking up the phone? [Aaron] was having a hard time reaching his wife, so he hacked up a solution. The Moshi Moshi detects calls from [Aaron], and plays music to get her attention.

A remote server running Asterisk picks up the call and uses a Ruby script to log the call. Every ten seconds, an Arduino Due with an Ethernet shield polls a Sinatra web server to see if a call has arrived. If a new call has come in, a music loop is played. Getting the Due to loop audio was a bit of a challenge, but the end result sounds good.

Quite a bit of tech is brought together to make the Moshi Moshi, and all the code is provided in the write up. This could be helpful to anyone looking to combine hardware with the Asterisk PBX. After the break, [Aaron] shows us how the system works.

This snippet of Hello World code lets [Nico Ritschel] turn the Pin 13 LED on his Arduino on and off using Siri, the voice-activated helper built into iPhones. The trick here is using the Ruby programming language to get Siri Proxy talking to Arduino via the USB connection. He calls the project siriproxy-arduino.

On one end of the hack resides SiriProxy, a package not approved by Apple which is capable of intercepting the Siri messages headed for Apple’s own servers. The messages are still relayed, but a copy of each is available for [Nico's] own uses. On the other side of things he’s building on the work of [Austinbv's] dino gem; a Ruby package that facilitates control of the Arduino. It includes a sketch that is uploaded to the Arduino board, opening up a Ruby API. The collection of code seen above defines the pin with the LED connected and then listens for a specific Siri commands to actuate it.

Take a look at [Nico's] explanation of the module in the video after the break.
