So i just bought a Arduino Leonardo and connected it on my pc seems to work because it recognises it as "Arduino Leonardo" so when i tried Uploading but didnt seem to work i got an error avrdude: Version"C:\Users\myusername\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/bin/avrdude" "-CC:\Users\myusername\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf" -v -V -patmega32u4 -cavr109 "-PCOM5" -b57600 -D "-Uflash:w:C:\Users\myusername3\AppData\Local\Temp\arduino\sketches\71570487F91002B1C6630EDBAC6FE9C2/Chinese-buttons-not-omron.ino.hex:i" 6.3-20190619 Copyright (c) 2000-2005 Brian Dean, [http://www.bdmicro.com/](http://www.bdmicro.com/) Copyright (c) 2007-2014 Joerg Wunsch ``` System wide configuration file is "C:\Users\myusername\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino17/etc/avrdude.conf" Using Port : COM5 Using Programmer : avr109 Overriding Baud Rate : 57600 ``` avrdude: ser\_open(): can't open device "\.\COM5": The system cannot find the file specified. avrdude done.

Did you select the correct board in the tools menu? The Leonardo uses a different com-port for uploading then for normal use. The upload port should be detected automatically during upload. The Com port shown in the IDE for normal use is not existent during upload. ---
