So I was looking through my "scraps" electronics box where i store uncategorized stuff, and I found an Arduino Uno. The only problem is it seems to not be responding in any way to anything, even resetting it with the reset button (aka the leds dont switch on or off). When i try uploading a sketch: …

There could be other things wrong but if you don't use a data cable then it will never work You could try uploading a sketch using the ICSP header but you will need extra hardware to do that

Welcome to the forum Does the PC recognise the Uno and create a serial port when you plug it in ? If so, have you selected that port in the IDE ?

Im not sure, but I dont think so

If no serial port is created then you can never upload a sketch to the board. Are you sure that you are using a data cable and not just a data cable ? Which Operating System are you using ?

I was using raspberry pi / linux / debian, but I also used ChromeOS & Windows and they both didnt work. I wasnt thinking about the cable though, I need to test that out

it also did show one port, so I assumed it did realise the arduno was there

Is that one port present when the Uno is not plugged in and does it appear when you plug it in ?

Ok, yes the port is visible without the Uno lol; Its probably a non data cable

Probably, thank you so much man
