Introduction: How to Add WiFi Control to Any Project || ESP32 Beginner's Guide

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how easy/difficult it is to use an ESP32 with the Arduino IDE in order to add WiFi control to any electronics project. Along the way I will show you how to use the ESP32 to create a simple WiFi server and how to create a fitting control app for your smartphone. Let's get started!

Step 1: Watch the Video!

The video gives you all information you need to add WiFi control to any of your electronics projects. In the next steps though, I will present you some additional information.

Step 2: Order Your ESP32!

Here you can find suppliers for the ESP32: (Mine is from the Ebay link)


Step 3: Upload the Code!

Here you can find the code/sketch that I created during the video. Feel free to download it and use it for your own projects.

Here are also useful reference sites for the ESP32 that I also partly used in the video:

Step 4: Install the App!

Here you can download the App that I created during the video for Android phones. But you can also easily create your own App with the MIT App Inventor:

Step 5: Success!

You did it! You just added a WiFi control to your electronics project!

    Excellent work-thanks for the guide!

    Thank You for this video! I've loved it (as most of yours :-) )!

    I'm planning to make a room thermostat (heating controller) with it. It should measure the floor temp, the ceiling temperature, the room humidity and room temperature. Room temperature should be set on it via buttons or touch sensor.

    The question for me is that can it handle one digital temperature sensor, one digital temperature and humidity sensor, the buttons, oled screen and a relay at the same time? I want to use it standalone, without Nano, if possible. Relay is not sure, if the job can't done without a central unit. In that case thermostat must be able to ask for heating and for (ceiling) cooling at a central unit, so must be able to communicate with it on wire. Wireless is used to monitoring and setting temperature.

    Thank You!

    Can you include the video link since the Android Instructable ap doesn't show videos otherwise?
