Cookie-IO Expansion Shield V2
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I purchased the Cookie I/O expansion board
how do I hook up ? I have the Arduino Uno board
DO I use the I2C ports and do I need a library installed
Also , why are the ports the same as the Arduino Uno , d1 , d2 ,d3
How do I specify the expansion I/O ports in the code...

You can plug the Cookie I/O expansion board directly into Arduino Uno board , You use the IIC protocol sensor to install multiple corresponding library files.The D1,D2...Pin directly connected to the UNO board,You canspecify the expansion I/O ports in the code like the Arduino UNO board.Please access this link get more information use Cookie I/O expansion board .https://www.dfrobot.com/wiki/index.php/ ...
