Hey.I have an arduino uno r3.the chip on board atmega328 is getting heated very quickly,is it normally like that?
And i would like to make a Usbasp with it.i googled a lot but found nothing :( .so please help me :D

ATmel328P-PU microcontroller should NOT become warn, that is, this is not a normal working condition.  Likely there is a defect/short that is causing the chip to sink or source too much current.  A defective, damaged, or miswired shield could be responsible.

USBASP can be managed with the Uno, see:

Also, there are other sketches besides the one listed above, you can search for those, but one nice one of note was written by Nick Gammon in the forum.

Fix the overheating chip first!

Is anything connected to the board headers?
The way you have it in your schematic isn't the same as how you have it wired up!
