Because you're sampling at specific time intervals, and the sampling is the same as the incoming carrier frequency, you might sample a LOW every time - you should sample a MINIMUM of 2.5 times the maximum frequency.electroniks said:I cannot think of a reason why. Would you please care to elabourate a bit ?
It makes hardly any difference, pretty well all IR remotes use similar wavelength diodes.concrete_hed said:Hey im new here, sounds like a cool idea. Just a quick question for ya. Dont some IR photodiodes only respond to certain wavelengths eg. 900nm? So what if the IR LED sends out a different wavelength to what the photo diode in an appliance can pick up? Does it matter too much if the wavelengths are different?
