Encoder made of touch contacts, prototype. Very economical version
!There were no errors in this board, everything works at once
You place the board in the desired position, secure it, and you can detect the movement of the object above the board (absolute position). You can use both contact and non-contact methods, e.g. through a plastic layer. Capacitive contacts are used. More information about contacts in the code. An example can be seen in the video
