Hey guys, I have to sum up some stuff for the project i've built for school
But unfortunately i can't find anything about the reset circuit and how it works online.
Can anyone explain please how is the reset circuit that is connected to PC1 working?

Thanks in advance. :slight_smile:

The description of the reset circuit is in the datasheet.

In the UNO and its variants, the only actual reset circuit as such is a capacitor which briefly pulls the reset pin low when the serial interface is opened and a resistor which pulls the line high - also a button to pull it low manually. All other reset functions (at power on) are handled in the chip itself.
