title: How to program an Arduino with I2C for a liquid crystal LCD screen?
body: <p>I am trying to get text characters to come up on my liquid crystal LCD screen. It's a 16x2 screen. It only uses four pins... GND, 5&nbsp;V, SCL, and SDA pins. I'm not sure how to program it since all I'm finding online is how to program it if my screen has 16 pins to connect for programming. I believe the address for my LCD screen is 0x27.</p>
