Everyone love the 1602 character LCD, is cheap and works out of box! But the need for 6 to 10 GPIOs is the pain :) It takes most of GPIO of Arduino and other microcontroller. Now with this I2C or Two wires interface LCD, you will save a lot of GPIO for your sensor and motor control.
This is a great blue backlight LCD display. As the pin resources of Arduino controller is limited, your project may be not able to use normal
LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, you can still program this LCD with the correct I2C address. It is fantastic for Arduino based project.
Note: If the display is not clear (or blank), try to adjust the contrast level by tuning the on-board potentiometer.
- I2C Address: 0x27
