/*
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
