I understand that LED brightness seems to be logarithmic as a function of duty cycle. In other words, perceived brightness = log(duty cycle) or that as the duty cycle becomes higher, the perceived differences in brightness become more imperceptible. A person on the AVR Freaks forum posted this thre…
