Wiring
Check pinout, power supply, common GND and voltage levels before connecting the module.
Full code
#include <Wire.h>
#include <Adafruit_BME280.h>
Adafruit_BME280 bme;
void setup() {
Serial.begin(115200);
bme.begin(0x76);
}
void loop() {
Serial.println(bme.readTemperature());
delay(1000);
}How it works
This lesson matches the page title and gives a clean starting point for this exact example.
Common mistakes
Check board selection, wiring, libraries, power supply and serial monitor baud rate.
