For deep-discharge protection, you can use the ADC. Another external ADC pin wouldn’t be of any benefit anyway. The avr tiny25/45/85 have the feature of sampling the internal 1.1v reference, relative to VCC. You can use this to figure out absolutely what voltage the avr’s VCC is sitting at, and once it hits 3.0v or something alike, call the powerdown routines – which use less than one onehundredth of a milliamp. If you want to be extra safe, shut it off at 3.3-3.4v. You’ll probably want not to use brownout detection, as having that enabled consumes extra power, even in deep-sleep, unless you specifically disable it in software before going to sleep.

This looks like a really cool toy! Thanks for sharing.

Seems like a great project. Is the PCB single layered or double layered?

It is a double layer board.

Both are ok. I used 100u on the board.

thanks!

In your circuit is 10u, but in parts list are 100u, where is mistake?

The motors are connected to JP1 and JP2.
