Hello In your earlier Esplora pin outs you show the orange tinkerkit outputs with the correct pin out it goes
5v | digital_out | GND
your latest 3.0 revision has it wrong and shows it:
GND | digital_out | 5V
I can assure you the latest 3.0 is incorrect and needs to be changed.
here is another reference that has been working for a long time now and I just hooked it up to my oscilloscope and i can assure you the current one is wrong.
