			==Burning fuses==
			Before uploading a program or concurrently, you might need to set 'fuses' on the micro-controller that control whether the chip uses its internal or external clock and other parameters. For example, the Atmel 328P micro-controller comes from the factory set to use its internal clock, so if you load a program expecting to use an external 16MHz crystal and then it seems to run slow, perhaps you didn't burn the fuses yet.
