Hey guys i have been studying pwm in arduino uno. The o/p in arduino uno is from y= 0 to 255 which can be used as pwm like this analogWrite(x,y); What i want to know is, is there any unit for this number 0-255? It must be related to duty cycle. Can anybody tell me how to calculate duty cycle?

PWM arduino uno problem?

The Wikipedia article is reasonably clear, and not too complex. Duty cycle - Wikipedia
