last chatshaala we discussing how to define any pin of microcontroller is input/ output(DDR).
In Avr microcontroller, 1 is use for an outputs and a value of 0 is Input.
if we want to configure all the Pins on PORT B as outputs, we would simply use the following code:
DDRB= 0xFF; (hexa decimal)
if we want to configure PB6,PB0 as outputs,
