I got that code from issue 104 of MagicPi
It's made for RBp Pico (micro python). But I want to do it on Raspberry Pi 3b+
It already bug at import machine. As such linbrary/module does not exist. Can someone help make it work.
import machine
import utime
import _thread
led_red = machine.Pin(15, machine.Pin.OUT)
led_amber = machine.Pin(14, machine.Pin.OUT)
led_green = machine.Pin(13, machine.Pin.OUT)
button = machine.Pin(16, machine.Pin.IN, machine.Pin.
PULL_DOWN)
buzzer = machine.Pin(12, machine.Pin.OUT)
global button_pressed
button_pressed = False
def button_reader_thread():
global button_pressed
while True:
if button.value() == 1:
button_pressed = True
utime.sleep(0.01)
_thread.start_new_thread(button_reader_thread, ())
while True:
if button_pressed == True:
led_red.value(1)
for i in range(10):
buzzer.value(1)
utime.sleep(0.2)
buzzer.value(0)
utime.sleep(0.2)
global button_pressed
button_pressed = False
led_red.value(1)
utime.sleep(5)
led_amber.value(1)
utime.sleep(2)
led_red.value(0)
led_amber.value(0)
led_green.value(1)
utime.sleep(5)
led_green.value(0)
led_amber.value(1)
utime.sleep(5)
led_amber.value(0)
