/* SparkFun Keypad Example Code

 This example code will quickly get you up and running with the 
 SparkFun U/D/L/R/Flame Keypad. Pressing the flame button will
 turn on/off the red LED. Up and down adjust the brightness of
 the LED. And left and right are just there to look pretty will
 output their status via the serial monitor.
 
 Multiple touches are not supported in this code.
