Thanks for the video. Gonna give this a try later on. Just wondering 2 things:
1) I would like to get this displayed to the 2 line LCD that comes with the kit. Do you know where I should start looking and reading to figure this out?

2) with the 3 pin DHT11, we don't need to use a resistor correct? But the 4 pin one we do need a resistor, correct?

Thanks again!

hello thanks for a great sharing. i have a question, after i upload and test run the program, humidity and temperature cant detect anything. how to fix it? thankss youre the best!

How did you get the dark mode? Otherwise great and a big sub

Hi all, is possible in this code in some way remove decimal places? I didn't found some code for showing/hiding decimal places in header file. Thank you.

Mine says failed to reed sensor
Please help

whenever i try this code it always says "An error occurred while uploading the sketch". Do you have any fixes for that?
