controling and displaying data in same time HELP !!

Other Hardware LEDs and Multiplexing
1

Hi for All i found some codes source on Net about iot and control over web using arduino so i modified it : the 1st source code its for send sensors data(DHT11,ULTRASONIC ) to ThingSpeak (open IoT platform) the 2nd its for controling over web page( relay , Led , servo ) the 2 sources codes work 100 % i want to make it in just one code so how is that I tried but its not worknig i neeeeeeed HELP

1st source code for sending sensors data to Thingspeak.com

Where is the code you tried that does not work? Post it and describe what happens. Give compile error messages and/or serial output (in code tags).

this is what i did but its not work

there is no compile error messages !!

Its hard to follow. Please use Auto Format in the IDE and post it again.

I see two ethernet.begin() calls in setup(). Don't know if that is causing a problem.

hi bro thanks

i repost the code with Auto Format tools

i dont know im not good in programming but i think arduino bored can't be worwk like server and client in the same time when i send data from arduino to thingspeak its work like client for ThingSpeak server and when i control ( relay , led, servo moteur ) over web page i think its work like server is that right ??

for ethernet begin() i just do copie past for code parts and made it in one code

:confused:
:confused:

I don't know any reason why Arduino cannot be both client and server, but I am not 100% sure they can because I have never done it. You are the second person to ask me that question recently. I will try to find time to settle the matter.

thanks bro i hope you can find the solution i really need this project for my education
