NikolaJE:
The LCD works and it shows the value the sensors had when I pressed the button, but it doesn't change until I press the button on the remote again. So i should just make separate codes and then when I want to use them in the If function for the Ir sensor and lcd I should just write something likelcd.print(DHT.temperature) ...?
OK. Things are better than I thought. Let me have a look on the code ...
