[HOWTO] PlainDSP audio shield: M2M Communication system

The Critical Tinkers team recently achieved an amazing application based on the plaindsp kit. The M2M protocol they developed provides a smart way to send information to an Arduino board using a plaindsp audio shield from any sound emitting device (e.g. a cell phone). Next video is a teaser which demonstrates the principle of operation, as long as your computer is not muted !
