 ## Pin
 It's very simple, just connect the first 6 pin of the lcd (RST, CE, DC, Din, CLK, VCC) to the Analog A0 -> A5 in Arduino Uno. And the 2 other pin are BL and GND, connect them to GND pin on Arduino. If you like backlight, connect BL to 3.3v (I use this because it doesn't take a lot of space!)
