OLED的尺寸還不少，常見的0.96吋和0.91吋都屬於SSD1106系列，但常見的就有一款1.3吋的，這就麻煩了，它是SH1106模組，函式庫無法共用，傑森習慣上用wonho-maker改寫自Adafruit SSD1106的函式庫，因為用法和Adafruit SSD1106幾乎相同，很方便。
只要是I2C介面的OLED接線都一樣，只有4條線，SDA、SCL接到Arduino Uno板上的A4、A5，VCC接到3.3V，GND接GND，就搞定了。
先下載wonho-maker的SH1106函式庫，下庫網址：
https://github.com/wonho-maker/Adafruit_SH1106
而這個函式庫還要Adafruit GFX Library函式庫來配合，所以請一併安裝。
因為要做圖形，會用到Image2LCD，Image2LCD下載網址：
http://www.e-paper-display.com/download_detail/downloadsId=625.html
程式和SSD1106幾乎一樣，比較細節的說明，請參考之前傑森寫的SSD1106的教學，這裡就不多說囉！

/*
* 本範程式為Arduino結合1.3吋OLED的範例程式，由傑森創工提供
* 本程式由wonho-maker改寫的Adafruit函式庫範例進行簡化，若需要進一步學習，建議參考sh1306_128x64_i2c範例
*
* 1，請先安裝Adafruit GFX Library函式庫，可由Arduino IDE裡的「程式管理員」進行安裝
* 2，請先安裝wonho-maker SH1306函式庫，下載網址：
