Not really a project, but interesting to anyone working with WLED: I plugged WLED on my fathers oscilloscope and watched the bits flip.
Pro tipp: setting WLED to a fade effect will help. I set it to a fixed color first and went into 1hour fiddling with the trigger asking myself “why do I get such a weird signal?” Once WLED sends something - which it only does when playing an effect - you get a signal.
1us resolution is good on the x-axis, 5v on y.
