OLED I2C analogPin dynamic plotting

Cool project to begin with OLED 128x64 work, done with a twisted logic to fix the refresh flashing screen.

Step 1: What You Need?

1 x Arduino UNO
1 x 128 x 64 Blue I2C IIC Arduino OLED Display

1 x Potentiometer (10k Ohm Resistor) 

1 x Arduino Breadboard 5V 3.3V Power Supply Module (for OLED)

1 x Breadboard

1 x USB Type-B Cable

Male-to-Male Jumper Wires (MM)  

Optional 

USB To Power Jack Cable

Don't have components? Don't worry. Just click the component's name. 

Step 2: Build Your Circuit.

Step 3: Download The Library & Upload The Code.

You need to download the libraries needed in the code below and uncomment one #define thing at the <Adafruit_SSD1306.h>

We comment the 128x32 define line and uncomment the 128x64 define line because our screen has 128x64 pixels of definition

Your library should end like that

Short scheme of how are the pixels maped in our screen:

The origin of coordinates is for some silly reason located on the top left of the screen and our function display.drawFastVLine cant draw negative heights so we are going to play with the cursor point along with the databar height

Step 4: Test Your Circuit.

Thanks for reading.
