![]() ![]() These libraries can be installed through the Arduino Library Manager. Install the following libraries in your Arduino IDE. Installing the ESP32 Board in Arduino IDE (Windows, Mac OS X, and Linux). ![]() We’ll program the ESP32 using Arduino IDE, so before proceeding with this tutorial you should have the ESP32 add-on installed in your Arduino IDE. Prerequisitesīefore proceeding with this project, make sure you check the following prerequisites. In this example, we’re using a two-way communication between two boards, but you can add more boards to this setup, and having all boards communicating with each other. Each board needs to know the other board MAC address in order to send the message.After sending the readings, the board displays on the OLED if the message was successfully delivered.When a board receives the readings, it displays them on the OLED display.Each board sends its readings to the other board via ESP-NOW.Each board gets temperature, humidity and pressure readings from their corresponding sensors.Each board is connected to an OLED display and a BME280 sensor In this project we’ll have two ESP32 boards.
