Arduino UNO with ST7735 160x128 TFT display example

Example circuit diagram and Arduino code:

Interfacing ESP8266 NodeMCU (ESP-12E) with ST7735S SPI TFT:

I have similar TFT LCD (red board) but my pin layout is like this:
VCC
GND
GND
NC
NC
NC
CLK
SDA
RS
RST
CS
I'm going to connect it to arduino uno r3 but i don't know whether i should connect the VCC of TFT to 5v or 3v of arduino.
This board doesn't have LED pin like other 1.8 TFT ST7735 board.

Please help.

Hi thank you for making this video.
Please could you post a link to your 1.8 inch display from AliExpress or Ebay or wherever you purchased from?

Thanks for this.
as of Apr 21, you may have to change:
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC);
to:
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, -1);
The -1 is a dummy for RST. The connection is optional.
