Im not too sure if this is the correct place to post this cuz i didnt see anything for errors, but i hope this can be solved. I am trying to make a race wheel for my pc out of the potentiometers i bought and the arduino and breadboard, everything is connected properly, but i did change the port com 3 while following the tutorial on youtube, i did everything successfully but now i cant upload the code. Ill post the error i get from arduino and the port name below. If you know how to switch back to com 3 please let me know.
If the board shows as 16U2 in Windows device manager, it more than likely indicates that the 16U2 TTL-to-USB converter is missing its firmware. I think it's the second time in the last few days that somebody is experiencing this issue.
@imcomin4u, did the board ever work correctly. If not, complain to the seller.
Do you have a programmer or other Arduino so you can flash the 16U2?
Ah, I see, thanks for taking the time to post an update with your solution @imcomin4u. So you had to put a custom firmware on the ATmega16U2 in order to use the USB HID capabilities to make the Arduino board act as a "race wheel".
