Hands-On Internet of Things with Blynk

By: Pradeeka Seneviratne

Overview of this book

Blynk, known as the most user-friendly IoT platform, provides a way to build mobile applications in minutes. With the Blynk drag-n-drop mobile app builder, anyone can build amazing IoT applications with minimal resources and effort, on hardware ranging from prototyping platforms such as Arduino and Raspberry Pi 3 to industrial-grade ESP8266, Intel, Sierra Wireless, Particle, Texas Instruments, and a few others. This book uses Raspberry Pi as the main hardware platform and C/C++ to write sketches to build projects. The first part of this book shows how to set up a development environment with various hardware combinations and required software. Then you will build your first IoT application with Blynk using various hardware combinations and connectivity types such as Ethernet and Wi-Fi. Then you'll use and configure various widgets (control, display, notification, interface, time input, and some advanced widgets) with Blynk App Builder to build applications. Towards the end, you will learn how to connect with and use built-in sensors on Android and iOS mobile devices. Finally you will learn how to build a robot that can be controlled with a Blynk app through the Blynk cloud and personal server. By the end of this book, you will have hands-on experience building IoT applications using Blynk.

Motor driver

The TB6612FNG Dual Motor Driver Carrier (https://www.pololu.com/product/713) allows you to drive a pair of small brushed DC motors. This type of motor driver is known as a full H-bridge motor driver. This driver can accept input voltage ranges from 4.5V to 13.5V to drive DC motors, and the logic supply voltage can be 2V to 7V.

A 1×16-pin breakaway 0.1″ male header strip is included with the TB6612FNG motor driver carrier. You can find more details about the breakaway male header at https://www.pololu.com/product/965. This strip can be soldered to the carrier board so that it can be used with solderless breadboards.

Once soldered, you can use it with a solderless breadboard. You can choose a breadboard to fit the size and shape of your robot chassis. Some breadboards offer mounting options, so you can easily mount them using standoffs. Pololu offers a wide...
