Understanding Arduino UNO Hardware Design
When trying to upload the bootloader to my Arduino Uno board, avrdude fails (see attached log). The reason seems to be that the extended fuse byte is not read correctly, because avrdude now read the unused bits as 1, which gives 0XFD instead of 0X05.

Extended Fuse Bits. Los valores por defecto el ATmega328p son: Low fuse = 0x62 (B01100010) High fuse = 0xD9 (B11011001) Extended fuse = 0xFF (B11111111) Los valores de los fuses de Arduino con el ATmega328p son: Low fuse = 0xFF (B11111111) High fuse = …

Repair Arduino Nano (no Power on USB): I shorted my arduino nano clone again, so its time to make a tutorial video, how fix this problem. The schottky diode: 0. 5A 20V SOD-123 housingThe video:1. Check the arduino. Isn't there a self healing fuse we can use. The normal Arduino uses it. …
How to reset ATmega328P fuses using Arduino Pro Mini and
The important thing is to setting the FUSE settings correctly depending on the type of Arduino board. The boards. txt in Arduino installation folder is useful for that. The FUSE settings can also make the chip un-readable if you want to protect your firmware a bit.
