Example usage:

/*

Example of LTM8328PKR04 library usage.

Connection:
  LTM8328PKR04 pins 3 & 8  --> to ground
  LTM8328PKR04 pin 4 (data) --> to Arduino pin 8 
  LTM8328PKR04 pin 5 (clock) --> to Arduino pin 9
  LTM8328PKR04 pin 6 (Vcc) --> to +5V
  LTM8328PKR04 pin 7 (dimmer) --> to +5V via 15kOhm resistor + 1nF capacitor if flickering occurs
  LTM8328PKR04 pin 9 (VLeds) --> to +3.3V
