The researchers used an Arduino Uno board, an Adafruit LCD, a desk fan and a household spray bottle to transmit a short message across a tabletop, via molecular diffusion.

A very unique Arduino project has been created by a team of researchers at Stanford led by post-doctoral fellow Nariman Farsad, which is capable of sending text messages using common chemicals.

The program could interface with Arduino through a serial port, and send data to Python, which in turn forwards it to your phone.
