It's a great material to learn the algorithm!
Very easy to set up, just put in 4 pins (GND, OUT1, OUT2 and OUT3) of the signal.
Type "OUT1" to turn on the green light!
OUT1 OK
I made CutleryCards for the Signal!
"CutleryCard - Signal pack (Japanese)"
"CutleryCard - Wait pack (Japanese)"
Try make your signal!
