This FingerStarterKit is including a Hall-Sensor option, which can detect a "touch" from the finger.
When the finger touch something, the servo starts sliding forwards and this will set the magnet closer to the Hall-Sensor.
The Hall-Sensor gives a linear voltage (2,5V is the default).
I'm using the SS495A sensor from Honeywell.
As magnet I'm using a 2x1mm (NeoDynamisch)
The servo is a Corona CS238MG Metal Gear Servo 4.6kg
To mount this servo, you need first to un-screw the four screws at the bottom-side!
If you like to use a ESP32 board, you need to use the ESP32_Servo library !
