Scripts for controlling playback on a Raspberry Pi.
You will need to have Gordon Henderson's WiringPi installed for these to work http://wiringpi.com
For a description of the hardware I wrote these for, see my blog at http://eastertrail.blogspot.co.uk/ and the schematic diagram PushButtonControl-schematic.pdf
These scripts and files are under a CC0 license, in other words in the public domain as far as permitted by law. You are free to do what you like with them, they are very simple!
