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:
Type
cd ~.Run the command
git clonehttps://github.com/simonmonk/raspirobotboard3.git—this will retrieve the library.Then type
cd raspirobotboard3/pythonto go to theraspirobotboard3/pythondirectory.Type
sudo python setup.py install—this will install the files.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)
...
