make plz help

Yes it will.

I don't think they charge for extra words in here. Erasure of the previous program is done by the bootloader, unless you've managed to trash it. If you trash the bootloader you have to rewrite it with an ISP tool.

Does the bootloader actually erase the previous program, or does it just overwrite the previous program with the new program? If I was designing it, I'd probably have taken the second approach, since that would be faster and easier and (perhaps) kinder to the flash memory.

Its not possible to do a bit-wise erase in this kind of FLASH, so you erase whole blocks at a time.

Use engllish, not eyfhuw378hvd3h, please!

Development platform use. New code write to microcontroller, overwrite old code it will.

(English sentences correct complete more better understand everyone.)

His instructables don't have such bad english.
