No Devices!
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
As shown in the picture below, I purchased three sensors, sen0470 , sen0467, and sen0231, and connected each sensor to Arduino UNO according to your online instructions.
There is only a message "No Device!" message. Can you give any advice?
