ESP32 + Python: From Microcontroller to IoT

ESP32 + Python: From Microcontroller to IoT
Artcal 0: Introduction

When it comes to transferring data from one place to another, things can sometimes become tricky, especially when communication happens between the hardware and software levels.

In this article series, I would love to share the experience and knowledge I’ve gathered while working with ESP32 and Python. We’ll explore how these two technologies can work together, starting from the basics and gradually moving towards more interesting and practical projects.

If you have any questions, suggestions, or ideas along the way, feel free to share them in the comments section below. I’d love to hear from you and discuss them with the community.

So, without further ado, let’s begin! 🚀

What is ESP32?

Think about Esp32 as a microcontroller with Internet facilities, consisting WiFi, Bluetooth and a own wireless data transfer protocol called ESP-NOW between ESP32 chips. Nowdays, the developers have made development boards integrading these chips for the easy use.

ESP32 is a family of microcontrollers developed by Espresiff. This can read sensor inputs, process data, contol devices and specially connect to the internet. This is like Arduino but better, faster and smaller. With these information that we have, we can speak about this board as,

"A powerful microcontroller that can interact with electronic components and communicate with other devices through Wi-Fi, Bluetooth, and other communication methods."

Python???
We use different languages to tell the same thing but in different ways. We use programming languages to tell the computer the same thing but in different approches. Some languages can be hard to learn and some are easy. Some are well developed and some are not.

Python programming language was created back in 1980s by Guido Van Rossum, with the development begining around 1989. It was publicly released in Feb, 1991.

🐍 1989 — Guido van Rossum developing Python.
🐍 1991 — The first public release.
🐍 2000 — Python 2.0.
🐍 2008 — Python 3.0 .

Python is a high-level, general-purpose programming language known for its simple and readable syntax. This allows programmers to write programs that can perform tasks, process data, and interact with other software, devices, and systems. It is widely used in areas such as web development, automation, data analysis, artificial intelligence, and hardware communication._

IoT
We interact with objects every day in order to complete our tasks. They all are connected to prefome a task. We're the onece who connect them together.
IoT simply refers to,

"Internet of things"

This refers to physical devices that can collect, exchange, and sometimes process data over a network(usually the internet).

In simple terms, IoT is about connecting everyday objects to the internet so they can connect, communicate and perform tasks automatically.

The Combo
The combination of these technologies are always like a cup and the tea.

The combination of ESP32 and Python brings together hardware and software, allowing them to work together to create interactive and connected applications. The ESP32 can collect data from sensors, control electronic components, and communicate over networks, while Python can receive, process, analyze, and display that data. Together, they provide a powerful foundation for building IoT projects and other hardware-software applications.

An ESP32 can read data from a temperature sensor and send that data over Wi-Fi to a computer or a server. Then they can process and get an action with those information as needed. This is an example of an IoT application.

Conclusion
We learned about ESP32, Python, IoT

In this article, we introduced the two main technologies we’ll be working with throughout this series: ESP32 and Python. We looked at what they are, what they can do, and how combining hardware and software can open up many possibilities for IoT and other practical projects.

This is only the introduction towards a greater communication. From next article onwards, we’ll start getting our ESP32 and Python knowledge with theory & practical examples. This is just our first steps toward making them communicate with each other.

We'll meeeeet soooooooooooon! 🚀
