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
