    Here my new FingerStarter kit with Hall-sensor option:

    FingerStarterKit with HallSensor option by MdG_NL – Thingiverse
    https://www.thingiverse.com/thing:2994206
    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 !
    For the Finger parts, please download the InMoov Index Finger via http://www.inmoov.frhttp://inmoov.fr/inmoov-stl-parts-viewer/?bodyparts=Finger-starter-kit
