Tutorial - LED Current Limiting Resistors
about 3 years ago
if i wants to use make a development board for atmega16
and i wants to put a power led in it.
then how will i calculate the value of current limiting resistor because there will be a extra resistance(effective resistance of other components) in parallel to the led resistance.
and the value of parallel resistance will not also be fixed
how to do that??????
