Chapter 4. Working with a RESTful API and Pulse Width Modulation

In this chapter, we will interact with the board with HTTP requests and we will use pulse width modulation to generate different output voltages. We shall:

Work with the Tornado web server to build a RESTful API in Python
Compose and send HTTP requests to print numbers in LEDs
Work with pulse width modulation to control the output voltage in pins
Fade in and fade out LEDs connected to the board
Use different tools to compose and send HTTP requests that interact with the board
Build a RESTful API to mix red, green and blue and generate millions of colors with an RGB LED
Use the mraa and wiring-x86 libraries to control pulse width modulation
