I agree that the brightness can be controlled by duty cycle if it is a single one. My question is how to achieve dissimilar brightness in a grid LED matrix by PWM/duty cycle methods. For example, if I want to display time in HH:MM pattern in which the HH part of the display to be more brighter than MM part. | |
