Contest: Logarythmic LED Fader by Reinhold Pieper
Here is an analog dimming circuit for a LED which takes into account the light sensitivity of the human eye (Weber-Fechner-law).
Here is an analog dimming circuit for a LED which takes into account the light sensitivity of the human eye (Weber-Fechner-law). For this purpose, the current through which the LED's rise logarhitmically and drops off again when switched off in reverse logarithm.
