I am using an arduino board to controll a led strip. 3 transistor and 3 resistors are between the board and the leds. 1 for each color (RGB). I am using analogWrite to change the brightness.
But I wanted to make the leds even less bright, without adding another resistor. I figured out that when i turn them on and off very fast they will not flicker but they will appear to be less bright.
Will this harm the leds? Or is this ok to do? Do other people also use this trick?
