I was working on a code to get the climate in my greenhouse automated. Everything was working fine until yesterday, i uploaded this code:

Serial.println(vocht);

I first made the code for all my sensors including:
- MHZ-14a
- HTU21D
- DS3231
- BH1750
OLED display included, then i combined the code with the part that controls all devices. Separatly the codes worked fine. Until i combined them, nothing would work like it was supposed to, but now my biggest problem that i cannot upload a new sketch to the arduino uno R3. Even when the IDE says the new code has been succesfully uploaded, the old code shown above keeps running.
I've mentioned this in another topic, but i thought i'd make a new one since they're different problems now.

NOTE: These instructions will not solve the problem. They are only intended to gather more information which might provide a clue that eventually leads to a solution.
