![Digital or Analog?
All physical quantities are analog.
Analog means that the quantity can take any value between its minimum value
and maximum value.Digital means that the quantity can take specific levels of
values with specific offset between each other.
Ex: 1 - Digital:
English consists of 26 letter, there is no letter between A and B.
- Square waves are Digital.
Ex.: 2 - Analog:
Temperature, can take any value[-1,12.8,25.002,… etc.].
- Sine waves are analog.](https://image.slidesharecdn.com/mindfiretechtalkiot-170502072217/85/Tech-Talk-IOT-9-320.jpg)

This document provides an overview of getting started with Internet of Things (IoT) development using Arduino and the ESP8266 microcontroller. It discusses what a microcontroller and Arduino board are, common Arduino board types like the Arduino UNO, sensors, the Arduino IDE, and IoT. It also covers the ESP8266 module, connecting it to the Arduino IDE, and provides an example IoT demo using the NodeMCU and Blynk app.

It is an open source hardware, anyone can get the details of its design and modify it or make his own one himself.
