pull_up_down=GPIO.PUD_UP issue - Raspberry Pi Forums

i have been working on script run photobooth have built wedding.

after testing 30 minutes or today started trigger photo preview sequence though button had not been pressed. test if being caused button removed it; still triggered on it's own.

removed pi , have connected monitor, keyboard, , mouse. have run script below see if can rule out mistake made in photobooth script.

code: select all

import rpi.gpio gpio import time  gpio.setmode(gpio.bcm)  gpio.setup(23, gpio.in, pull_up_down=gpio.pud_up)  while true:     input_state = gpio.input(23)     if input_state == false:         print('button pressed')         time.sleep(0.2)

code getting "button pressed" on , on again without button being pressed.

perhaps know causing this?

what have got connected gpio 18?
