Hello brand new .. take it easy on me. I want to read digital inputs over wifi on myUNO REV 4 wifi , and I have not been able to find any examples or tutorials. I have theSImpleWebServer example, which works to turn the onboard LED on and off and I have DigitalInputPullup, which reads the status…

Hi @realolman . There is an example sketch named "WiFiWebServer" that comes with the "WiFiS3" library of the UNO R4 WiFi board. This sketch does almost exactly what you want, except that it provides the analog readings from the pins on the board instead of the digital readings. But it would be trivia…

[image] realolman: I would like to read the status of input pins over wifi... I think you have the wrong concept of what you want. You must have some computer or micro-controller to READ the input pins and send that data over wifi to your UNO REV4.

Unfortunately i see what i wrote is exactly what you read I want to read the inputs on my UNOrev4 wifi with my laptop over wifi I will have 5v on or off connected to digital inputs on my arduino and i want to be able to “read” them on my windows 10 laptop in some usable manner. Using wireless wifi…

Exactly the same situation. If you want a program in your PC to read a value, you must have a PC program to tell your UNO to read and then send that value to your PC. There is no magic.

Take a look at telemetrix . It handles all serial communications, and once you set a digital pin as an input, all data changes on that pin are automatically reported. Telemetrix provides a Python API. Here is a sample: import sys import time from telemetrix import telemetrix """ Monitor a digita…

Yeah im trying to find out how to do that. Do you know how?

No, never done it on a PC or an Arduino. But there are lots of threads on the forum relating to your project.

You are going to need some kind of protocol like mqtt, http, udp, sockets etc.... Then write a program on the pc to talk to your board. Your board will have a program that talks to your pc over the protocol. Think of wifi as just the carrier frequency. Or you can use the cloud services where there…

Yes… I would like to know specifically how to do that… I don’t expect anyone to answer this completely… I’m new to Arduino but I have been messing with this sort of thing for forty years… I don’t know how to “do” wifi… I have a tiny amount of experience with C+ and HTML I just don’t know how to do m…

This appears to me to be a great big BINGO! Thank you very much It was the very last thing on the list of examples and even now I had a hard time finding it...it was hidden by my taskbar.... That's a poor excuse I know ...and I thank you very much, ptillisch .. that is exactly the kind of help I h…

Thank you Mr Y
Is this wifi?

I don’t want to use serial
I have a labjack and it works well but im trying to lose the wire between the microcontroller and the computer
