When a mechanical switch closes it's contacts typically do not close "cleanly" and tend to bounce or chatter. This rapidly switching signal could be misread in certain situations so it is usual to attempt to reduce this bouncing to ensure a clean switch detection. the danger is that if the switch is not de-bounced you can detect multiple events from one opening or closing. Can be accomplished using analog circuits or digital circuits.

How is this Pushbutton Debounce code?
I can't put code in a comment, hence an answer. My 'framework' for simple embedded systems is the main loop with polling. To minimize current consumption the main loop can wait let's say 50 ms in idle …

Capacitor and ISP issue
A simple solution could be to connect the junction of C5 and R1 via a 10k resistor to PB2, and connect the ISP connector directly to PB2.
This is a general solution that you can use whenever you want …

Debouncing by ignoring data?
But it can be even simpler: I always debounce by reading the pin(s) at least 50 ms apart. Simple and effective.
That does indeed introduce a latency of up to 50 ms. …

Debouncing buttons
But when you already have a microcontroller you can debounce in software at only the cost of a some code effort. … The essiest way to debounce in software is to check the buttons at moments in time that are further apart than the longest bounce time. 50 ms seems to be an upper bound on the bounce time of 'normal' switches …
