Arduino was working properly in my system. After I uninstalled and reinstalled it again I was unable to connect arduino to windows 7 32 bit. There is no problem in arduino but pc isn't recognising it. Please guide me
I would suggest READING THIS post then adding any additional details.
There are multiple reasons for not being able to see an Arduino.
- There is a problem with the board.
- You have something connected to pins 0 and 1.
- The USB cable is faulty in some form.
- You do not have the correct driver installed.
- There may be a problem with the PC.
- You may be selecting the wrong COM port.
There will doubtless be others too.
The forum has a good search feature which will gather up relevant results in Google for you.
