/* LED test program 
  Alan Marchiori
  Bucknell University
  tested on Rev1.1 HydroSense Wireless Link board
  with PCA9634 on i2c address 0x20
  using a TeensyLC MCU on Arduino 1.0.6 (with Teensyduino installed)
  The teensy uses the library i2c_t3 for i2c communication
  instead of the usual "Wire" library. If using a standard Arduino, you will have
  to manually change the inculdes to use Wire. The libraries should be mostly
  compatible. (some calls are "enhanced" in the i2c_t3 library, these will have
  to be modified appropriately as well).
