I have just been given a 4tronix initio. I got a battery which was very week and when I connected the arduino it did not started. After this since I couldnt get bttery I could get a thing which could provide 12v. The arduino didn't start :(. After this I connected my laptop charger and it almost burned up but the arduino didn't do anything. This is a link tp the thing which i got. 4tronix initio.
Can anybody tell me what the problem is?
