Overview of this book

This Learning Path takes you on a journey in the world of robotics and teaches you all that you can achieve with Raspberry Pi and Python. It teaches you to harness the power of Python with the Raspberry Pi 3 and the Raspberry Pi zero to build superlative automation systems that can transform your business. You will learn to create text classifiers, predict sentiment in words, and develop applications with the Tkinter library. Things will get more interesting when you build a human face detection and recognition system and a home automation system in Python, where different appliances are controlled using the Raspberry Pi. With such diverse robotics projects, you'll grasp the basics of robotics and its functions, and understand the integration of robotics with the IoT environment. By the end of this Learning Path, you will have covered everything from configuring a robotic controller, to creating a self-driven robotic vehicle using Python. • Raspberry Pi 3 Cookbook for Python Programmers - Third Edition by Tim Cox, Dr. Steven Lawrence Fernandes • Python Programming with Raspberry Pi by Sai Yamanoor, Srihari Yamanoor • Python Robotics Projects by Prof. Diwakar Vaish

Using the Flick HAT


Flick HAT comes in the form of a shield, which you can simply plug into your Raspberry Pi and start using. However, once you do that, you will not be left with any GPIO pins. Hence, to save ourselves from that problem, we will be connecting it using male-to-female wires. This will give us access to the other GPIO pins and then we can have fun.

So, go ahead and connect it as follows. The following is a pin diagram of the Flick board:

Thereafter, make the connections as follows: 

Once the connection is done, simply upload this code and see what happens: 

import signal
import flicklib
import time
def message(value):
   print value
@flicklib.move()
def move(x, y, z):
   global xyztxt
   xyztxt = '{:5.3f} {:5.3f} {:5.3f}'.format(x,y,z)
@flicklib.flick()
def flick(start,finish):
   global flicktxt
   flicktxt = 'FLICK-' + start[0].upper() + finish[0].upper()
   message(flicktxt)
def main():
   global xyztxt
   global flicktxt
   xyztxt = ''
   flicktxt = ''
   flickcount = 0
