Touch input

Touch sensors

The Micro:bit includes 3 pins that can be used as touch sensors.

This test is done by measuring how much resistance there is between the pin and ground. A low resistance gives a reading of True. To get a reliable reading using a finger you may need to touch the ground pin with another part of your body, for example your other hand.

Pin0-Pin2 are touch pins.

    else:
        display.show(Image.SAD)
