Thanks for a super detailed tutorial with resources I found it very useful. I didn't disconnect my crystal when I switched back to internal oscillator and it didn't seem to interfere with the internal oscillator.

Boy, how I wish I had found this a few years ago! I suffered greatly screwing with the fuses. I really had no idea that my Arduino board was clocked at 1MHz factory! I was sure it was 8, or 16! Finally, you have made the fuse biz much clearer. So, when we burn the bootloader on Arduino, what are we doing? Really enjoyed how you showed an external "clock".

Great tutorial. A top down view on the breadboard would help a lot.

Hey Chris, I like the fast paced tutorials you're doing, but as I'm totally new to this, it would be nice to see the full size video so I can see exactly where the oscillator went. Remember you know this stuff and I'm trying to learn, a video in the corner is difficult to see.

I have a question on the Atmel Ice Programmer. since it does not supply voltage to the chip, does the Vcc pin on the Atmel Ice connector configured as an input pin where I would supply it with whatever 5volt DC source I am using as well as connecting my ground to the ICE ground pin on the connector?

Guys, how many chips did you break when touched fuse settings? I just broke the second chip in my life by changing CKSEL fuses in non-inverted mode in AVRdude

hi, I need help... i programmed an atmega8 (succesfully) with a "blinking led" code but it seems to be working at 3.3V... I want this microcontroller to work at 5V, ... I'm using a 5V power supply (it gives 4.8V actually), and I'm programming this uC with the pololu programmer...

How can i use a crystal 16MHz?
Is it the same configuration?

Which external oscillator are you using?

[surendramaharjan]

What if I don't have ATMEL-ICE Debugger? I am using Arduino-Uno. Can you help to set fuse to convert from internal to external oscillator?

Hi I have question about defining F_CPU in C code and as an option for avr-gcc compiler. What is the difference? Are these values always the same or are there situations when they are different. And thank you for one of the best and most comprehensive video tutorials on youtube

Hi, Is there any way to convert program written for Atmel to Arduino??
