Hi my name is Rami am from Syria and is my first post here, I'm studying communication engineering and I'm working on a junior project about ( car mirror with memory ) that saves the locations of a car mirror for many drivers ..
i'm using Atmega-16 to do this with keypad and L293 Motor Driver and LCD
every thing went well but the PROBLEM is :
How can i know the position of the DC motor ?? ( read the position )
how to read it ?? what device ?? what method to have values for motor positions back to Microconroller ??
I can't add a resistor to bring the value ( rotation ) from motor because I'm working on regular and fixed car mirror ... and normal DC motor .. non-step one
the solution should exist somewhere in my circuit
my project reached a dead end
any useful ideas please ?
many many many thanks 4 all
sorry about my English :)
