Alright guys, this is just an intro, no diagrams or wires.

First of all, this is going to be a series of articles, step-by-step we will learn everything ESP32 has to offer.

I'm actually a web developer, proficient with programming in Python and JavaScript, and somewhat C/C++.

Resolution 2025

I'd decided to learn more about micro-controllers in 2025, like ESP32, or Arduino Uno, or whatever, but I want to learn something. That's my one of the goals for 2025.

I will be writing articles on this blog here as I learn, but why ESP32?

I just asked ChatGPT, to give me the detailed report on both, ESP32 and Arduino Uno, and then I asked to compare them, and then I asked some random questions and decided to learn about ESP32.

The goal is not just to sit on the computer and do the programming. But, is to tap into IoT, later on (maybe after 2025).

My Reasoning

I checked the price on several platforms, including marketplaces, and for me, both of they are very cheap. But as I read the report, I tried to compare IoT tools' price, and it is ridiculous.

Say I bought ESP32 along with some other sensors and wires, and so on, it costs me around $20 to $50 (upper limit, cost is actually much lower).

Now, I have thermostat in my house, which costs me around $150 to $300. Higher cost because it allows me to change the temperature using my phone. It is connected to my wifi, and it is kind of smart.

So, I paid around 5 to 15 times higher.

Well, this is just rough calculation, it also depends on a lot of factors. A basic minimal thermostat costs around $50 to $70 and works just fine.

Another Example,

I have seen cars with parking assist, or let's just consider the easy case. Say, if anybody/anything comes closer to back of your car, your car will beep, indicating there is someone/something behind you.

Can I add this feature to my car if it does not already have it, using ESP32?

Can I add a back-camera and a display, everything connected to ESP32?

Can I add a tracker on my bike, which shows me it's live location on my phone?

At the end, I am a web developer, I should be able to spin up some servers and manage a hell lot of ESP32(s) and process a lot of data.

So my question is why not?

Let's get started then.
