Accuracy of Stepper Motors
I think that in the first post '%' mean degrees. If number of steps to turn is too less gear can be used. If you use a worm gear, you may get number of steps to turn as big, as...

Retrieve data during Power off/RESET
1) At start of program read stored data position by position data and find position with last time. 2) You must know size of memory region used to store data, if end is reached...

Shift register with SPI/USI
595 can be used with AVR's spi interface working in 0 mode. Usually with 595 I use 4021 as inputs. My code for initialisation: static inline void spi_init(void) { SPCR =...

Problem in c programming [can I use C++ ?]
C++ is a superset C. If you know C++, you know C too. You only must avoid some language constructions (eq. classes and overloadind). Find in library good book about C and learn...

Regulator is overheating ....
I often use a resistor before 7805. Resistance of it is that, as at maximum current input voltage for 7805 is ~7.5V. This resistor must has adequate power, of course.
