I just recently bought 3 Nano V3.0, Nano Board ATmega328P 5V 16M Micro-Controller Board Compatible with Arduino IDE (Nano x 3 with USB Cable) by LAFVIN and I tried to create a humidity and temperature display on my breadboard with it. At first, I plugged it in, changed the board to Arduino Nano, but the usual Port 4 with the board was not there on the port list. I looked something up and installed the CH340 driver to try to fix things and it now shows up at port 5. Whenever I tried downloading code into the nano, it either seemed to download except it has no function with other components, it had a never ending cycle of trying to download, or it just had an error message and refused to load at all. I have already tried using it with the old bootloader setting with no avail. The error message:

avrdude done. Thank you.
