Although I have had my Arduino for quite a long time, I still haven't done much with it at all but today after looking at this(http://yourduino.com/Photos/ArduinoUno-CU-1024.jpg) photo of a standard arduino UNO I realized that on my arduino, there is a missing connection on what I believe to be a transistor, the one next to the power input as highlighted by this (http://i.imgur.com/dPDZr.jpg) photo. There is simply no connection at all soldered on.
This hasn't caused me any problems so far, but still, I would prefer if I fixed this. What problems could this lead to? Is it worth me just trying to put some solder on? (I have no soldering experience!)
Thanks in advance, ell.
Do I need to mark this question as [solved] or delete it or anything?
