Hi i am Khuzaima ,i would like to get details on interfacing avr 8515 microcontroller with stepper motor on avr studio ..My friend seminarprojects.org said interfacing avr 8515 microcontroller with stepper motor will be available here and now i am living at karachi pakistan and i last studied in the Govt.national college pakistan and now am doing BS in electrical from national university of computer and emerging sceinces i need help on interfacing a stepper motor with avr micro processor we can step both on clockwise or anti clockwise direction etc

This AVR tutorial will discuss interfacing Light Emitting Diodes with Atmel's AVR series of Microcontrollers. A LED is an acronym for Light Emitting Diode and is basically a electronic device which emits light when an electric current flows through it. The electronic symbol for a LED is : LED Symbol
General purpose LEDs used in digital circuits require around 75mA or less and so we usually use resistors to limit the current flowing through the LED when it is connected within a circuit as shown below. The resistance of the resistor is calculated using the well known formula V=IR.
