Test a 16*2 LCD display with I2C module interfacing with arduino uno

Category: Arduino Compatible Kits Tags: 16*2 LCD DISPLAY, Arduino Uno, I2C module

KIT INCLUDES:

In this project you will see how to connect i2c LCD display to arduino and how to print on LCD display.

Each I2C bus consists of two signals: SCL and SDA. SCL is the clock signal, and SDA is the data signal. The clock signal is always generated by the current bus master; some slave devices may force the clock low at times to delay the master sending more data (or to require more time to prepare data before the master attempts to clock it out). This is called “clock stretching”

SPECIFICATIONS

I2C LCD Serial Module

IC/I2C Interface Adapter Module is used for 16×2 LCD Display. It uses the PCF8574T IC chip which converts I2C serial data to parallel data for the LCD display. Also this interface module simplifies connecting an Arduino to a 16×2 Liquid Crystal display using only 4 wires.

Supply Voltage: 5V
Interface: I2C
Compatible for 16×2 LCD
Brightness and Contrast can be adjusted by the Potentiometer

**16*2 LCD**

LCD Display Mode: STN, Positive, Transflective
Display Color: Deep Blue/ Yellow Green
Viewing Angle: 6H
Driving Method : 1/16 duty, 1/5 bias
Back Light : Yellow-Green LED backlight
Outline Dimension: 803615.8 MAX
