    If you just don't have enough digital I/O pins on your Arduino to interface with all your sensors and controls, you might want to look at using the I2C bus to connect a few port expander chip PCA8574AD have 8 digital I/O bits and can be set to addresses 0x38-0x3F respectively.
    The I2C bus on the Arduino uses SCL, SDA, a couple of pull up resistors and the Wire library.
    You can connect more expander module. More 8 modules. Just change adress of each module.
    On back side of board have instruction.
    If you need more connecting modules, pls cut off the connection of pull-up resistor on back side of board. Only 1 board need pull-up resistor.

    Technical Supports:

    • Simple Codes, Libraries and Examples
    • Data sheets, Application Notes and References

    this tutorial will help you use the module ,and despite the diffidence between our module and the one in it but the main chip is the same:
