If you need to create a BMP280 component from scratch:

Default is 0x76 (SDO to GND) or 0x77 (SDO to 3.3V).

Connect the pin of the BMP280 to the A5 pin (SCL) of the Arduino Uno.

You may have pasted the library files into the wrong directory. Ensure you used the ProgramData folder rather than the Program Files installation folder for Proteus 8. Always restart Proteus after adding new library files. To ensure your simulation runs perfectly, let me know:

Note: In Proteus, ensure the BMP280 is correctly powered. Because BMP280 is a sensor, it is critical not to feed to the VIN pin. 3. Programming the Arduino for Proteus

Proteus often simulates I2C perfectly without any pull-ups. Real hardware requires external 4.7kΩ resistors on SDA and SCL lines. Many beginners wonder why their code fails after simulation—this is a top cause.

Serial.print("Pressure = "); Serial.print(bmp.readPressure()); Serial.println(" Pa");
