Motor start when initiate?

[Oeil2L]

Hello,

I had many difficulties to do the wiring. Now it seems to work as expected, but I'm still not sure about my wiring. So the project isn't connected to the table.

Main point for me, when I initiate on button, motor start for few seconds during the appearance of 8888 sequence, is it normal as initialization process?

Thanks for yours feedbacks.
