I2C interface for 16x2 / 20x4 LCD display

I2C interface for 16x2 / 20x4 LCD display

Product information:

Because the number of pins on an Arduino is sometimes just not enough, there is now the I2C display interface for connecting a display.
With this interface you only need 2 outputs (SDA/SCL) to drive a display. This leaves the rest free for shields and sensors.

Using the LiquidCrystal library (see programming example) you can easily put text and custom characters on the screen.
Download the library and place the extracted folder in your My Documents/Arduino/libraries .

Among the programming examples you will also find the I2C_Display_test which will allow you to get your display working right away.

The I2C address is by default 0x20 or 0x27 (check this with the i2c_scanner programming example under documentation) but can be set on the interface with a simple solder bridge to an address from 0x20 to 0x27. Set the found I2C address for the display in your sketch (I2C_ADDR).

Suitable for 16x2 / 20x4 displays.

Dimensions: 82x35x18 mm
Supply voltage: 5V

Tip: First test the combination of the interface and display by connecting them together without soldering. (With a foam pad between the prints it will stay in place temporarily.)
