@moustafa_nabil, this forum is for Particle devices which are WiFi and GSM based. I believe you are looking for an Arduino forum! :grinning:

@moustafa_nabil, well I see that you have two good choices. One, buy a Photon which can replace your data collecting Arduino and possibly your server since now you will have cloud connectivity out-of-the-box. The Particle community will be more than willing to help!

Or, you can do a search for an Arduino forum where you may find the answers you are looking for. :wink:

Just to wet your apertite to replace the duinos :slight_smile:

Client

int oldval = 5000;
void loop()
{
    int val = analogRead(A0);
    if (val != oldval)
    {
        Particle.publish("myEvent", String(val), 60, PRIVATE);
    }
    delay(1000);
}

Server

void setup()
{
    Particle.subscribe("myEvent", myHandler, MY_DEVICES);
}

void myHandler(const char *event, const char *data)
{
  int val = atoi(data);
  analogWrite(A0, val);
}
