In this project, we’ll build an ESP32 client that makes an HTTP POST request to a PHP script to insert data (sensor readings) into a MySQL database. We’ll also have a web page that displays the sensor readings, timestamps, and other information from the database. As an example, we’ll be…

This week’s project topic is related to Web Server. We’ll take a look at how ESP32 can communicate over WiFi and have it control certain thing from its web server. Introduction ESP32 standalone web server controls output, in our case is BMP280 sensor reading and LED status. …

In this article, we’ll take a look at wireless short range communication protocol that is Bluetooth, both classic and low energy variant, on ESP32. We’ll cover one experiment for each of the Bluetooth variant. Introduction Bluetooth is a wireless technology PAN standard used for exchanging data between fixed and mobile devices over…

Halfway through the semester and so far, I have covered quite a lot of things here on Medium related to embedded system and yes, today we’ll take a look at another new component which is display. Introduction Display is an electronic device used to visually shows electronic images, videos, and texts…

In the previous article, we talked about the in-built sensors of ESP32. This time, we’ll delve deeper onto the another type of sensor — external sensor. …

ESP32 Sensor : Internal Sensor Fifth week of college and here I am writing my third embedded system projects. This week’s topic is, as you can see from the title, ESP32 internal sensor. Introduction ESP32 has 3 built-in sensors: Touch sensor Hall-effect sensor Temperature sensor* *Not all ESP32 are equipped with…

Hi there and welcome! Another week another project and this time I’m working on a simple ESP32 I/O project, that is to read digital input from a push button switch to control digital output which in this case is an LED lamp. So the main objective of this project is…

Hi! Welcome to my first blog! I’m writing here on Medium for the very first time and yes, it is for my uni assignment. I am currently taking Embedded System course where I basically have to do certain ESP32-related projects and write everything I have to say — the preparation…
