For Python users:
Step 2: Change directory
cd /home/pi/Sunfounder_SuperKit_Python_code_for_RaspberryPi/
Step 3: Run
sudo python 08_rotaryEncoder.py
Now, gently rotate the encoder to change the value of the variable in the above program，
and you will see the value printed on the screen. Rotate the encoder clockwise, the value
will increase; or rotate it counterclockwise, the value will decrease.
