Hands-On Robotics Programming with C++

By: Dinesh Tavasalkar, Lentin Joseph

Overview of this book

C++ is one of the most popular legacy programming languages for robotics, and a combination of C++ and robotics hardware is used in many leading industries. This book will bridge the gap between Raspberry Pi and C/C++ programming and enable you to develop applications for Raspberry Pi. You'll even be able to implement C programs in Raspberry Pi with the WiringPi library. The book will guide you through developing a fully functional car robot and writing programs to move it in different directions. You’ll then create an obstacle-avoiding robot using an ultrasonic sensor. In addition to this, you’ll find out how to control the robot wirelessly using your PC or Mac. This book will also help you work with object detection and tracking using OpenCV, and guide you through exploring face detection techniques. Finally, you will create an Android app and control the robot wirelessly with an Android smartphone. By the end of this book, you will have gained experience in developing a robot using Raspberry Pi and C/C++ programming.

Implementing Blink with wiringPi

After setting up the Raspberry Pi, it's now time to connect different electronics components to it and program it using the C++ programming language. To use C++, we will first have to download and install a library called wiringPi.

In this chapter, we will cover the following topics:

  • Installing the wiringPi library inside the Raspberry Pi
  • Making an LED blink
  • Smart Light—working with a digital sensor
  • Pulse Width Modulation using softPwm
