How to Setup an IC2 Display to Arduino

Introduction: How to Setup an IC2 Display to Arduino

Have you ever wanted to hook up an LCD display to Arduino but found out its really difficult. Well this is how I hooked it up so you can follow along and easily connect a display to arduino to print out information easily

Step 1: Wiring the Connections

For wiring the connections you will need to wire arduino to your lcd and this is how

SDA to A4

SCL to A5

Gnd to Gnd

Vcc to 5v

Step 2: Finding Your IC2 Bus Address

This address is necessary in order to allow your arduino to effectively talk to you display and this address can be found by simply running this code:

and then going to serial display and chang the baud to 11520. Then type in s and enter. Now scroll up to get your address.

Step 3: Programming Your IC2 Display

Now in order to do this you will first need to go to sketch, include library, manage library and download liquid crystal IC2. After this you can use my program that took 10 seconds to throw together and edit the bus address to yours and edit the text to what you want it to say.

my code:

    i found the solution: i was working with a Arduino Nano. You can only do this with a uno
