This is easy and worked even on the old ESP8266 boards. Since there is WiFi on the board, the simplest thing we can do is connect to an existing WiFi network. Except for this, the usage of this board is no different from any ordinary Arduino.Īll code examples in this article are fully ready to use, and you can simply copy and paste them into the Arduino IDE. I can only note that it’s needed to press and hold the Boot button to upload the code from the Arduino IDE. I will not describe how to connect the ESP32 to the Arduino IDE, anyone can read it here. For testing, we will need any ESP32 board (preferably with an OLED screen, as in the picture) and Arduino IDE. I will consider different options for using WiFi, from a simple connection to a home network to a WiFi sniffer.
