In this video we will talk about what fuses are, what they are for and how to work with fuses on AVR microcontrollers. In the video I will demonstrate the fuse calculator and how you can change fuse bits with the fuse calculator.

I will show an example of changing the fuses on the ATtiny13 microcontroller. But this method will work for other AVR microcontrollers too. In the video, I will first change the fuse of the CKDIV8 and show what happens. And then I will show the result of changing the RSTDISBL fuse. And you will see how easy it is to increase the number of available I / O pins by one.

An Arduino UNO is used as an ISP programmer with a module placed on top for the convenience of firmware ATtiny microcontrollers.
