Then we create a website page with a button.

This will have two columns, one called ID and another one called status and they both have integer values. For example we create a simple table and name it LED_status. This database will have columns and rows and we can store data on it. For that I usually use A database is just like an Excel file but is on an online server, we call this "the cloud". This is a learning tutorial so I will use a free hosting and server which is a bit slow. For the rest of the settings make sure you have the ones below if you're using the same DEV board as I am. Now if you go once again to tools, boards, you can see that we can now select between a lot of ESP32 boards.

Select these boards and click install and as you can see I already have them installed. Now go to tools, boards and click the boards manager. Then go to preferences and in the extra URLs you have to paste this link from below. Let’s make the ESP32 work with Arduino so open your Arduino IDE. Connect it to your PC and make sure your windows will install the drivers for the FTDI chip which in this case is the CP2102. This ESP32 development board already has that configuration and a USB connector together with an FTDI programmer IC so we can program it directly. This controller works at 3.3V and to be able to program it we need a basic configuration with some pullups and buttons. The EPS32 microcontroller has WIFI included adn the board is very small and you can get it from HERE. Together with that we will make a website platform and control stuff using the internet. That’s great, right? Also, different to my previous videos, this method will be a lot more secure because instead of GET method we will use the POST method which uses encrypted data and is a lot more secure. And to make it all easier, instead of using AT commands, we will use the HTTPclient library from Arduino IDE so the code would be very easy. Is very small, very powerful, very fast because it’s 32 bits and works at 80Mhz, and best of all, it has WIFI included. Today we start with the ESP32 microcontroller. Using AT commands the code was very, very long and difficult to follow and most of you guys weren’t able to establi sh a good connection with the servers. And that’s because I was using the ESP8266 and AT commands. That’s because that tutorial was a little bit difficult to follow. I’ve made such project a few years ago, but I get a ton of questions about that video. IOT is very common nowadays, and is very interesting.

We learn how to get from an ESP32 to a cloud database and from the internet back to the ESP. Today I start a new and very interesting video series about IOT or internet of things.
