I have a LED whos power i want to control by PWM, 1khz. Duty cycle adjustable from 20% - 50%.
This LED points at a sensor.
This sensor is sampled at a rate of 25khz.
Im struggling to get my head around whether the sensor will consider the LED to be a digital series of pulses, or one analog signal.
Can any of the clever Trevors on this forum offer any advice? Websites to look at or whaterver. Its more important to me that I understand whats going on, than whether I get the correct answer.
Cheers
