2.6 Tilt It!


The tilt switch is a 2-pin device with a metal ball in the middle. When the switch is upright, the two pins are connected; when it is tilted, the two pins are disconnected.



When you put it upright, GP14 will get high; after tilting it, GP14 will get low.

The purpose of the 10K resistor is to keep the GP14 in a stable low state when the tilt switch is in a tilted state.





  • Open the 2.6_tilt_switch.py file under the path of kepler-kit-main/micropython or copy this code into Thonny, then click “Run Current Script” or simply press F5 to run it.

  • Don’t forget to click on the “MicroPython (Raspberry Pi Pico)” interpreter in the bottom right corner.

  • For detailed tutorials, please refer to Open and Run Code Directly.

import machine
import utime
button = machine.Pin(14, machine.Pin.IN)
while True:
    if button.value() == 0:
        print("The switch works!")

After the program runs, when you tilt the breadboard (tilt switch), “The switch works!” will appear in the shell.
