Noise, per se, is seldom the reason for random switch ons. Collisions
between two valid codes, spikes on the powerline (e.g. UPB data, fluorescent
ballasts, motors) and brownouts (e.g. sags from motors starting) causing the
microcontroller to reset are the most likely causes. The probability that
random noise can create a valid Manchester code is near zero.
