	Note that you'll find a couple of different I2C addresses floating around, like <code>0x20</code> and <code>0x27</code>. I'm not sure where people are getting those from, but the <code>0x3F</code> value comes from [http://www.sainsmart.com/sainsmart-iic-i2c-twi-serial-2004-20x4-lcd-module-shield-for-arduino-uno-mega-r3.html Sainsmart's website], and it works right out of the box.
