Hi
I'm a real beginner at arduino, I just use it when I really want to make something so it's been a long time since I've tried to connect.
I blew up a little controller I'd made for my coolbox so I bought a couple of new Nano boards and I can't connect them to anything.
I usually use a raspberry pi because I live in a van and it uses less power. I have used this pi with both uno and nano plenty of times but now I can't connect to either of the new boards or the one I found still in a new packet, probably a year old. I can connect to one I use for a disco light, so it's pretty weird that it works with that one only. However, I also have a Windows 10 laptop and I have the same issue.
I have tried selecting (old bootloader) on the Atmega 32P option, in fact I've tried every combo of USB ports and options.
Either it says "avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xe0" or it will spend eternity uploading but not succeeed.
I've read a lot of comments about this and drivers, so I've tried using board manager to roll back the versions of the boards in case they are too old for the most up to date version, but as I said, I'm a beginner and this is a shot in the dark.
I've read about changing the baud rate but I can't figure out how to do it.
Is it more likely a fault in the boards?
I'd really appreciate some pointers as I'm just stuck now
In Linux, does lsusb show the board when it's connected?
In Windows, use device manager to check.
Is whatever port you selected in the IDE the correct port?
There is a third option under tools → processor; some clone Nanos might be shipped with a 168 instead of a 328P; worth a try.
Link please to what you bought.
Thanks
I've looked in device manager and it shows 'unknown device' so I followed advice on forums to look for the old drivers in the install files. I found them in a zip file that windows wouldn't let me open! In the end, I reinstalled the IDE with the board attached in the hope that it would detect the board and install the correct drivers. No luck.
The nanos came in a bag with Atmega 328P written on, but in fact I have tried a hundred different settings!
I'm also having issues with my trusty UNO (again, since updating) but as nothing shows in device manager and no ports at all show up in the IDE, I'd initially assumed that the cable was defective or something.
I've sent one of the nanos off with my son to plug into his desktop - I'm sure it's a driver or setting issue, those nanos are almost new and I can't see any reason for them being faulty as well as the uno.
I know this is boring to experienced coders etc but I bet there are hundreds of people like me trying to connect devices and just getting frustrated, so figuring this out would be marvellous

sorry I don't have that link but it wasn't the cheapo ebay ones! It was a reliable source
on the Raspberry PI run lsusb.
Look for anything that contains brltty
if you have it try this:

if you use accessibility settings this will remove them.
sorry for the late reply everyone, thanks for your suggestions, I think the issue was to with USB drivers after the update. A least, I got a message saying that the update was incomplete due to being done over mobile hotspot - when I tried it with a friends braodband it fixed itelf and has been fine since. I don't know why this happened!
