After running my code my Oled freezes and my sensors stop working. The OLED freezes displaying the last values of the sensors. All values of the sensors however are correct. Any help appreciated. Arduino Uno Gas Sensor: 5V, GND, A0 BMP Sensor: 5V, GND, SCK A5 and SDI A4 DHT Sensor: 5V, GND, …

So actually, I just tried 20 SDI , 21 SCK for BMP and after switching everything over to the Mega 2560......EVERYTHING works as intended now!

Freezing issue - Arduino Uno: Oled, Gas Sensor, DHT, BMP280
