Flask is a micro web framework written in Python that allows you to build web applications easily and quickly. As we know python is a general purpose programming language and it can be used to implement many different network protocols and models To establish the connection, you can’t just connect the Google Assistant to the microcontroller directly. We need to use two interfaces to establish the connection between the Google Assistant and the ESP32. In this project, we will connect ESP32 to the free public MQTT broker operated and maintained by EMQX MQTT Cloud, and use the Arduino IDE to program the ESP32. E In this project we will be sending the temperature data to the Arduino IoT cloud so that you can access it from anywhere in the world . We will be using DHT 11 sensor to send Temperature and Humidity data to Arduino Cloud. The NodeMCU_ESP8266 has a total of 30 pins, with 17 of them being GPIO pins, which stands for General Purpose Input Output.

We will be sending the temperature data to the Arduino IoT cloud so that you can access it from anywhere in the world Martials needed. IoT for Juniors - Project 8: Controlling LED from a web-page
Here we are making the project where the esp8266 will give a webpage on IP address and from that page we can control the LED which is connected to pin13(D7) of nodeMcu. IoT for Juniors - Project 5: Controlling AC appliances with Arduino Uno
5v Relay: A 5V relay module is an electronic component that can help you control high voltage circuits with a low voltage signal, such as an Arduino.
