BME280 I2C Test.ino
This code shows how to record data from the BME280 environmental sensor
using I2C interface. This file is an example file, part of the Arduino
BME280 library.

Connecting the BME280 Sensor:
Sensor -> Board
-----------------------------
Vin (Voltage In) -> 3.3V
Gnd (Ground) -> Gnd
SDA (Serial Data) -> A4 on Uno/Pro-Mini, 20 on Mega2560/Due, 2 Leonardo/Pro-Micro
SCK (Serial Clock) -> A5 on Uno/Pro-Mini, 21 on Mega2560/Due, 3 Leonardo/Pro-Micro

You can’t perform that action at this time.
