understanding the reset button on the uno...

hi, can someone explain what happens to the current sketch on a uno when I press the reset button on the uno board please.

Does it clear the uno memory in readiness for another sketch or does it go back to the start of the current sketch and restart the sketch?

thanks for any help in getting me to understand, as a complete newbie, what's happening on the uno...

It resets the currently-loaded sketch, and runs it from the beginning.
(This is not a troubleshooting and installation topic)

Thank you for your help.

Which forum is most suitable for my newbie q's please?

Probably the microcontroller section.

I have moved it to the Microcontrollers board.

There is no one forum board for "newbie q's". Just read through the descriptions of each of the boards and pick the one that seems most appropriate for your question.

thank you, all above.
