Sorry for hand drawn schematic.
Want to know if my calculated values are right?
As there is no feedback from servo decided to use switches normaly open to get feedback from shaft location at extremes. Depending of what pin will send a signal to attiny it will trigger predefined isr to control direction of the motor shaft rotation. When motor will hit one of the switches attiny will power off motor and save position in eeprom for future reference. I want to power motor from 6v to accelerate shaft movement compared to 5v. Im also not sure if signal voltage 5v is right if servo itself is powered from 6v.
Switches are connected through simple debouncing rc ~100ms.
Its battery operated circuit so power efficiency is my concern.
Update: i cant attach image from my iphone! Will update the topic with image as i get to my laptop. Sorry
