ESP32 Tutorial

Reddit's API has been piquing my curiosity for some time. However, my past experiences with APIs, especially with Twitter and Facebook have left a bad taste in my mouth. Then one day I had the courage to try it again and to my surprise, it's far easier than it looks!

Launching a project into production doesn’t mean it’s 100% finished --- this is why software/firmware updates exist. And your users are not programmers so you want the update process as user-friendly as possible. Thankfully, the ESP32 allows you to update its compiled code, called firmware, to be updated over the …

If you've been following my tutorials on ESP32, then you'll notice that the WiFi SSID and password are always hardcoded. This tutorial will show you a way to change the WiFi credentials without needing to edit and re-upload your sketch. Our aim is to create a simple ESP32 WiFi manager. …

With its WiFi capabilities, the ESP32 can connect to API services and acquire useful (and sometimes useless) information from the web. Here’s a quick tutorial on how to connect to RESTful APIs using ESP32.

This ESP32-powered project allows you to write messages to a MAX7219 LED matrix display using your smartphone. Scaled up, this can be used as a WiFi message board for schools or signages for businesses.

For this article, I will show you how to use an ESP32 microcontroller as a magnetometer - a device that measures the direction and strength of a nearby magnet. In the absence of a nearby magnet, the device detects the Earth’s magnetic field. Hence, a compass is a type of …

The ESP32 has become one of my favorite microcontrollers as it's compact, relatively cheap and contains 125% higher memory than an Arduino UNO.

Last time, I showed you how to setup the ESP32 development board with the Arduino programming environment. This time, I will be building a simple ESP32 web server where data from a sensor is displayed on a web page.

The ESP32 expands the capabilities of the popular ESP8266 WiFi microcontroller by using a 32-bit microprocessor, and adding Bluetooth 4.2 among others.  What possible projects can we build using this device? We will find out as we start our series for the ESP32.
