The Printed circuit has been realized with traditional components for a better didactic use. Below is the component serigraphy and then the side branches. To notice in the upper left side, in the outlined part, the space for a Plastic of contour to the contacts in order to locally program the keys. Moreover the tracks of the signals, on the lines of connection with the remote key hole (therefore also from a distance of 100 meters), have been realized with some points towards mass in order to "unload" eventual high tension disturbs followed obviously by lines of delay always realized with the tracks (Last image low to right)
