The library So I’ve written a library for the ESP32 that will take care of all the dirty nitty gritty aspects of playing back a wav file. The only thing I will say about it is that it will change in the near future as I add more features to it and some functions may or may not change as it develops.

The clock and the data pins connect to the EPS32 I2C pins as shown above. Get BMP280 sensor readings using ESP32. In this first step, we will read the data from the sensor (BMP280) connected to the ESP32. This is very simple. First of all, we have to import the Adafruit Library to manage the BMP280.
