The hardware is ready, now you can access all this functionality from Raspberry Pi Zero. First, install the library associated with the control board, found at http://www.monkmakes.com/?page_id=698 and perform the following steps:
Run the command
wget https://github.com/simonmonk/raspirobotboard2/raw/master/python/dist/rrb2-1.1.tar.gz. This will retrieve the library.Then, run
tar -xzf rrb2-1.1.tar.gz. This will unarchive the files.Type
cd rrb2-1.1. This will change the directory to the location of the files.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 drive motor and the steering motor. The code will look similar to the following screenshot:
The specifics on the code are as follows:
import RPi.GPIO as GPIO: This will import theRPi.GPIOlibrary, allowing you to send out a PWM signal to the front steering mechanism.import time: This will import thetimelibrary, allowing...
