RTTTL Library for Particle devices

A RTTTL (RingTone Text Transfer Language) Song player for the Spark Core, Photon and other Particle devices.

• Requires pin used to be a PWM pin because the library uses the tone() function
• Originally written by Brett Hagman (http://roguerobotics.com),
• Reworked by Technobly (http://technobly.com) for the Spark Core.
• Converted into a class by Chee Zhiquan(http://zv.sg) for Spark Core. Added stop, pause, play functions so the user can pause, replay or restart the song at anytime.

To play the output on a small speaker (i.e. 8 Ohms or higher), simply connect a 220 - 1k ohm resistor from the output pin (D0) to the speaker, and connect the other side of the speaker to ground. Or use a Particle Internet Button which has an on-board tiny speaker already connected to D0.

You can get more RTTTL songs from: http://code.google.com/p/rogue-code/wiki/ToneLibraryDocumentation or just search google for "your song RTTTL" or "your song RTTL".

Compile and flash to a Particle Internet Button with a Photon

Simple start/pause/stop player

particle compile photon examples/demo1/demo1.cpp src/RTTTL.cpp src/RTTTL.h --target 3.3.1 --saveTo play.bin; particle usb dfu; particle flash --usb play.bin

Full featured player takes new song requests via Particle function or publish, plays several songs in a loop on boot
