SPI OLED with Ardiuno

Image
                   Hi. Today I show you how to use OLED Display with Arduino UNO . first of all, you need an Arduino board and an OLED Display. OLED DISPLAY   There are many types of OLED displays by color & type of connection. In this   experiment, I   used a 128*64 blue color SPI OLED display. Arduino Board   In this    experiment,  I used Lakduino UNO    which is   an Arduino compatible board . But you can use any Arduino board for this like pro, Nano, Leonardo etc. Connecting Display to Arduino My OLED Display has 7pins.  OLED                  Arduino     GND   ------->   GND     VCC    ------->  3.3v     CLK    ------->   D12     MOSI  ------->   D11     RES     ------->   D10     DC       ------->  D 9     CS       ------->  D 8 * However, my display worked without connecting GND and VCC. Compile and upload code to Arduino now we're going to upload the code for Arduino. to do this you need Arduino IDE , Adafruit-GF
