Angle Sensor Ball Switch Tilt

🎮 Display the Raw Digital State

Goal

Read the tilt sensor and display its raw 0 or 1 value on the PC.

Concepts

Digital Input · HIGH/LOW · Loop · Serial Output

import machine  # Controls the board hardware
import time     # Controls pauses and timing

pin26 = machine.Pin(26, machine.Pin.IN)  # D2 reads the tilt sensor

while True:  # Repeats forever

    state = pin26.value()  # Reads the sensor state

    print(state)  # Sends 0 or 1 to the PC

    time.sleep(0.2)  # Waits before reading again

🎮 Level or Tilted

Goal

Interpret the digital value and display Level or Tilted on the PC.

Concepts

Digital Input · If/Else · Loop · Serial Output

import machine  # Controls the board hardware
import time     # Controls pauses and timing

pin26 = machine.Pin(26, machine.Pin.IN)  # D2 reads the tilt sensor

while True:  # Repeats forever

    state = pin26.value()  # Reads the sensor state

    if state == 1:  # Checks if the sensor is level
        print('Level')  # Reports the level position

    else:  # Runs when the sensor is tilted
        print('Tilted')  # Reports the tilted position

    time.sleep(0.2)  # Waits before reading again

🎮 Report Only State Changes

Goal

Report the sensor state only when it changes between Level and Tilted.

Concepts

Digital Input · Variables · Comparison · State Change · Serial Output

import machine  # Controls the board hardware
import time     # Controls pauses and timing

pin26 = machine.Pin(26, machine.Pin.IN)  # D2 reads the tilt sensor

last_state = pin26.value()  # Saves the starting state

while True:  # Repeats forever

    state = pin26.value()  # Reads the current state

    if state != last_state:  # Checks if the state changed

        if state == 1:  # Checks if it changed to level
            print('Level')  # Reports the new state

        else:  # Runs if it changed to tilted
            print('Tilted')  # Reports the new state

        last_state = state  # Saves the new state

    time.sleep(0.05)  # Waits before reading again

🎮 Measure Tilt Duration

Goal

Measure how long each tilted period lasts and display the duration on the PC.

Concepts

Digital Input · Timing · Variables · State Change · Serial Output

import machine  # Controls the board hardware
import time     # Controls pauses and timing

pin26 = machine.Pin(26, machine.Pin.IN)  # D2 reads the tilt sensor

while True:  # Repeats forever

    if pin26.value() == 0:  # Checks if the sensor is tilted

        start = time.ticks_ms()  # Saves the tilt start time

        print('Tilt started')  # Reports the new tilt

        while pin26.value() == 0:  # Waits while it stays tilted
            time.sleep(0.01)  # Adds a short pause

        end = time.ticks_ms()  # Saves the end time

        duration = time.ticks_diff(end, start)  # Calculates tilt time

        print('Tilt time:', duration, 'ms')  # Sends the duration to the PC

    time.sleep(0.05)  # Waits before checking again

🎮 Tilt Activity Monitor

Goal

Count tilt events and report both the duration of each tilt and the time between tilt events to the PC.

Concepts

Digital Input · Counter · Timing · Variables · Serial Output

import machine  # Controls the board hardware
import time     # Controls pauses and timing

pin26 = machine.Pin(26, machine.Pin.IN)  # D2 reads the tilt sensor

count = 0  # Stores the number of tilt events
last_tilt = time.ticks_ms()  # Stores the previous tilt time

while True:  # Repeats forever

    if pin26.value() == 0:  # Checks if a tilt begins

        start = time.ticks_ms()  # Saves the tilt start time

        between = time.ticks_diff(start, last_tilt)  # Finds time between tilts

        count += 1  # Adds one to the tilt counter

        print('Tilt:', count)  # Shows the tilt number

        print('Time between:', between, 'ms')  # Shows time between tilts

        while pin26.value() == 0:  # Waits while it stays tilted
            time.sleep(0.01)  # Adds a short pause

        end = time.ticks_ms()  # Saves the end time

        duration = time.ticks_diff(end, start)  # Calculates tilt duration

        print('Duration:', duration, 'ms')  # Shows the tilt duration

        last_tilt = start  # Saves this tilt time

    time.sleep(0.05)  # Waits before checking again
