Overview of this book

The whole world is moving from desktop computers to smartphones and embedded systems. We are moving towards utilizing Internet of Things (IoT). An exponential rise in the demand for embedded systems and programming in the last few years is driving programmers to use embedded development boards such as Beaglebone. BeagleBone is an ultra-small, cost-effective computer that comes with a powerful hardware. It runs a full-fledged Debian Linux OS and provides numerous electronics solutions. BeagleBone is open source and comes with an Ethernet port, which allows you to deploy IoT projects without any additions to the board. It provides plenty of GPIO, Anlaog pins, and UART, I2C, SPI pins which makes it the right choice to perform electronics projects. This gives you all the benefits of Linux kernel such as multitasking, multiusers, and extensive device driver support. This allows you to do programming in many languages including high-level languages such as JavaScript and Python. This book aims to exploit the hardware and software capabilities of BeagleBone to create real-life electronics and IoT applications quickly. It is divided into two parts. The first part covers JavaScript programs. The second part provides electronics projects and IoT applications in Python. First, you will learn to use BeagleBone as tool to write useful applications on embedded systems. Starting with the basics needed to set up BeagleBone and the Cloud9 IDE, this book covers interfacing with various electronics components via simple programs. The electronics theory related to these components is then explained in depth before you use them in a program. Finally, the book helps you create some real-life IoT applications.

Chapter 10. Internet of Things using Python

In the last chapter, we learned about different buses supported on BeagleBone. In this chapter we are going to take our physical computing exercises to the next level. In this chapter we are doing similar Internet of Things (IoT) exercises in Python that we did in Chapter 7, Internet of Things with BeagleBone. However, we will go one step further to upload and visualize our sensor data on the remote cloud. All our programs will be done using the Flask web framework. We will also implement a web app using the popular REST. The theory about the IoT is covered in Chapter 7. So, we will move to the programs directly. We will also cover security and other aspects in the last part of this chapter.

This chapter will cover:

  • Flask web application framework

  • Program to display temperature remotely

  • Program to control an LED through a web browser

  • RESTful web app to control a servo motor

  • Program to trigger an e-mail alert on over-temperature

  • Upload sensor data on cloud...
