Hi Franz

First of all my special Solus Chess board isn't an auto sensory board but uses tactile switches and I think this is where the confusion lies.
It is probably my fault as I have referred to it as a sensory board instead of a tactile switch board. So pressing down on one of the boards squares is like pressing two computer keyboard keys together or just clicking on the screen with a mouse.


First photo is of one of my tactile switches that lies underneath my very flexible plastic board.

The second photo is the wiring diagram that I used for the switches that connect to the Teensy USB Developement Board that contains Bergers code.

The third photo is the underside of my board showing the wiring and Teensy Board and how simple everything is.

Regards
Bryan
