Cytron NodeMCU Starter Kit (Blynk)

Overview

This IoT Kit is powered by a powerful microcontroller, the NodeMCU ESP8266. With the onboard ESP8266 module, running various IoT projects using different types of sensors and actuators will not be a problem. With all the components provided in this kit, you can explore IoT with the Blynk platform by completing sample projects. This tutorial will walk you through, step by step, how to complete the syllabus of this Cytron NodeMCU Starter Kit!

What is Arduino IDE?

Arduino IDE is a user-friendly software for programming boards, allowing users to write & upload code easily. With the ESP8266 board, which has internet connectivity, users can create projects that communicate online. The Arduino IDE supports the ESP8266, making it simple to write and upload code for internet-connected projects. For those who don't have the Arduino IDE, you can install it here.

Setup Arduino IDE for ESP8266

1. Open Arduino IDE software.  

2. Go to File > Preferences.

3. Copy the link below and paste it into the Additional Boards Manager URLs tab then click the OK button.
