Can we show its terminal via 7 segment? Or do u have idea to make HMI for that?

Which switch do i should use? NC or NO?
Then why we use 2 switch?

Just add the button as another gpio input then this input goes high reset the counting variable to zero.



Can you give me example in my python code for clearing my data without quit teriminal? I dont know how to make it.

Then, can we put time while the sensor detected object? because I need to count cycle time ( time between 2 detection object). or can we add to program to count that?

Yes, my sensor output when low signal is 0, then when the object detected is 1. Thanks for your help. Next question, can we make a button to clear all data and make it start again without exit from terminal? because i will implement this sensor using raspberry pi without keyboard and mouse. so that ...

Why if I run your code I get this from the first execute before my sensor sense?

Proses Tapper Roll ke 0
Proses Tapper Roll ke 1



Can we start from "Proses Tapper Roll ke - 1"?

Hi, I have a problem with my code in python. I use E18 D80NK proximity sensor for counting item. I need to rwrite output just when the output changes from 1 ti 0 or 0 to 1. My code now writes every time when sensor read the input. Example: Menunggu Proses ke - 1 Menunggu Proses ke - 1 Menunggu Prose...

Hi there, I have problem when I run my python code in teriminal. I always get continously counting with or without input from sensor. my code: import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) GPIO.setup(25, GPIO.IN) count = 0 # wait for sensor trigger loop while Tru...

I have a problem when i try to build a simply project with raspberry using opc ua protocol.


when i try to run a program, at the output "merah_0" is true, but at raspi client can't switch on the lamp who i use to be output

https://1drv.ms/u/s!AhJi7ZY1kVa3hAIcYabxoTW-kbnz I have problems, when i try run this programs, at QX output "merah_0" has "TRUE" value in client, and i try to connect with raspi, but at gpio raspi can't switch on the lamp. I use opc ua client and server to communicate all of them and used 4diac to...
