 # PiLEDlights
 For the Raspberry Pi - Make LEDs blink on network and/or SD card/USB storage activity.
 
-hddledPi blinks a LED on any mass storage access. Not only on SD card access, but also on USB thumbdrive and hard drive activity.  
-netledPi blinks a LED when there is activity on any network interface. Not only the built-in ethernet interface, but also on any other USB ethernet or WiFi interface.  
+hddledPi blinks a LED connected to a GPIO pin on any mass storage access. Not only on SD card access, but also on USB thumbdrive and hard drive activity.

 actledPi blinks the Pi's ACT led on all mass storage I/O, i.e. not only the SD card.
 
-netledPi and hddledPi make use of Gordon Henderson's wiringPi library - wiringpi.com - so you have to have that installed in order to build the programs. actledPi is a standalone, no special libraries are needed.
