==Introduction==
EASY plug 1602 I2C module is a 16 character by 2 line LCD display with blue background and white backlight. This LCD is ready-to-use because it is compatible with the Arduino Liquid Crystal Library. The original 1602 LCD needs 7 IO ports to be up and running, this easy plug design makes the wire connection easier than ever.<br>

Keyestudio EASY plug 1602 LCD Module


Introduction

This is a basic 16 character by 2 line LCD display with white text on blue background. On the back comes with a potentiometer to adjust the screen contrast. You can use only one line for simple connection.
This module should be used together with EASY plug control board.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.

Extension Experiment


Tilt Controlled Counting

Next, let’s get started with a little bit more complicated experiment.
For instance, use a tilt sensor to control the 1602 LCD show the counting. Let’s get started right now!

Hookup Guide
Connect the EASY Plug LCD module, two LED modules and a tilt sensor to control board using RJ11 cables.

Test Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.

What You Should See
Done uploading the code, if tilt the sensor, the red LED is turned on, and you should see the number showed on the first line of 1602 LCD will plus 1 per second, and ++ is displayed on the second line.

thumb

If tilt the sensor to another side, the white LED is turned on, and you should see the number showed on the first line of 1602 LCD will subtract 1, and -- is displayed on the second line.
