okay. this is rookie, but I wanted to know how the LEDs in mouse changes its colors
I know that applying different potential differences, across those LEDs produces different colored light
but what is the basic electrical component that varies the potential difference like that ? is it a transistor ??
and how can one make a simple circuit in which an LED will turn on and turn off in a specific time period
and how is DC inverted to AC, when concerned with low power
