Module 9: IOT Platform - Blynk

Introduction

Blynk is a platform that allows you to create and control IoT applications using a smartphone, tablet, or web browser. You can use Blynk to connect various hardware devices, such as Arduino, Raspberry Pi, ESP8266, ESP32, and others, to the internet and interact with them through a graphical user interface. Blynk provides a widget library that you can drag and drop to design your application, including buttons, sliders, displays, charts, and more. You can also use Blynk to monitor and analyze data from your sensors, send notifications, and integrate with third-party services.

By using Blynk with the ESP32, you can easily and quickly prototype your IoT projects without writing complex code or dealing with network protocols. You can use Blynk to control ESP32 outputs, such as LEDs, relays, motors, and more, as well as read inputs from sensors like temperature, humidity, light, and others. Blynk also allows you to create custom functions and logic for your ESP32, such as timers, triggers, and actions.

Setting Up Blynk

Please download the Blynk app on your smartphone. For more information on how to register an account, create a template, configure datastreams, set up the web dashboard, and configure the mobile dashboard, you can watch this video tutorial.

Blynk Syntax

Blynk events are actions that occur when you interact with your Blynk application or when your hardware sends or receives data from the Blynk server. You can use Blynk events to control the logic and behavior of your ESP32, such as turning devices on or off, reading or writing data, performing calculations, and more. You can handle Blynk events using Blynk library functions and Arduino sketches.

The Blynk library provides several functions you can use to handle Blynk events, such as:
