Overview of this book

The ESP8266 Wi-Fi Module is a self contained System on Chip (SOC) with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This book contains practical recipes that will help you master all ESP8266 functionalities. You will start by configuring and customizing the chip in line with your requirements. Then you will focus on core topics such as on-board processing, sensors, GPIOs, programming, networking, integration with external components, and so on. We will also teach you how to leverage Arduino using the ESP8266 and you'll learn about its libraries, file system, OTA updates, and so on. The book also provide recipes on web servers, testing, connecting with the cloud, and troubleshooting techniques. Programming aspects include MicroPython and how to leverage it to get started with the ESP8266. Towards the end, we will use these concepts and create an interesting project (IOT). By the end of the book, readers will be proficient enough to use the ESP8266 board efficiently.

Tweeting data from the ESP8266 board

This recipe will look at how to tweet sensor data directly from the ESP8266 board. To show you how to do it, we are going to use an ESP8266 board to tweet temperature readings from the DHT11 sensor, through the Temboo platform.

Getting ready

The hardware setup will require the following components:

Mount the ESP8266 board onto the breadboard. Then connect one leg of the photocell to the 3V pin of the ESP8266 board and the other leg to the 1 kΩ resistor. Connect the 1 kΩ resistor's other leg to the GND pin of the ESP8266 board, so that the photocell and resistor make a voltage divider circuit. Then connect the junction of the photocell and resistor to the ADC pin of the ESP8266 board.

The setup will look like this:

How to do it…

Refer to the following steps:

  1. Log in to your Temboo account. The first page that you will land on will be the libraries...
