-====== I2C LCD Display ====== 
-I bought an I2C display on ebay and by the description it seemed it just might work out of the box... But it didn't ...  
-Here is a description of how I got it to work, so next time I do not have to invent the wheel again. 
-{{ :​projects:​sainsmart_iic-i2c-twi_serial_2004_20x4_lcd_back.jpg?​200|}} 
-My display has a PCB on the back labled "​YwRobot Arduino LCM1602 IICV1" but it appears it is the same as the the one of [[http://​​sainsmart-iic-i2c-twi-serial-2004-20x4-lcd-module-shield-for-arduino-uno-mega-r3.html|]] 
-The only difference is the text on the back.  
-There were a few (simple) steps in getting the display to work, you just need to know what they are. 
-But first, here is a demo of the LCD display

-===== The Hardware ===== 
-The display works on an I2C interface. There is a board on the back that takes I2C signals and translates them in to a parallel signal. The display its self is originally a parallel display. 
-The I2C address is "hard wired" of the address: **0x27**
