Controlling R2D2 using the Raspberry Pi in Python

The hardware is ready; now you can access all this functionality from the Raspberry Pi. First, install the library associated with the control board, found at http://www.monkmakes.com/rrb3/. Perform the following steps:

1. Type cd ~.
2. Run the command git clone https://github.com/simonmonk/raspirobotboard3.git —this will retrieve the library.
3. Then type cd raspirobotboard3/python to go to the raspirobotboard3/python directory.
4. Type sudo python setup.py install—this will install the files.
5. Now you'll create some Python code that will allow you to access both the DC motor to turn the top and/or light the LED. Here is that code:

#!/usr/bin/python 
import time 
import RPi.GPIO as io 
from rrb3 import * 
 
io.setmode(io.BCM) 
 
forward_pin = 27 
backward_pin = 22 
led1 = 24 
led2 = 23 
 
def forward(): 
    io.output(forward_pin, True) 
    io.output(backward_pin, False) 
 
def backward(): 
    io.output(forward_pin, False) 
    io.output...
