Install dragit

Before any operations, you need to log into the Raspberry Pi remotely first. Here's how:
1． Get the IP address of the Raspberry Pi:
https://www.raspberrypi.org/documentation/remote-access/ip-address.md
2． Log in with the IP address, by ssh or VNC:
For ssh: https://www.raspberrypi.org/documentation/remote-access/ssh/README.md
For VNC: https://www.raspberrypi.org/documentation/remote-access/vnc/README.md
Now you're on the RPi already. Open a terminal for command lines. Let's see what's next.

1. Type in the command below:

 wget https://s3.amazonaws.com/sunfounder/Raspberry/dragit_installer.py

2. After download is done, type in the command to run:

 sudo python dragit_installer.py

3. Then you can see what to install. Switch to the one you'd like to install by the arrow key, and check the box by Space bar.
To apply the sensor kit with Dragit, you only need to install the top one, Install Dragit.
