Your python code exit at the end.

You didn't put any loop to prevent the code to exit!

add the function pause() at the end

Code: Select all

button.when_pressed = take_photo
pause()

or make a loop

Code: Select all

try:
    while True:
        time.sleep(0.010)
except KeyboardInterrupt:
    pass

You'll need the following at the start:

Code: Select all

from signal import pause

thank you, but I still want to ask about line 6, is there an error and is there a button, what about it?

Your 'with picamera...' is wrong.

Code: Select all

import picamera 
from time import sleep
from gpiozero import Button
from signal import pause

from picamera import PiCamera
camera = PiCamera()

button = Button(14)

def take_photo():
    print('take_photo')
    camera.start_preview()
    sleep(0.3)
    camera.capture('/home/strom/image{0:04d}.jpg')
    camera.stop_preview()
    
button.when_pressed = take_photo

pause()

thank you, it works, I still want to ask how to make it take another photo instead and not overwrite the old one? Thank you

You could add date and time to the image name:

Code: Select all

import datetime

camera.capture('/home/strom/image'+datetime.datetime.now().strftime("%Y%m%d-%H%M%S")+'.jpg')
