Esiste esempio (sketch) Cosm --> Arduino ?

International Italiano Generale

Ciao a tutti, grazie delle risposte.
Cosm ha messo a disposizione un nuovo sketch (data gennaio 2013), il quale ti permette di inviare un valore su Cosm, e allo stesso tempo rileggerlo, sempre con il medesimo sketch.
E un punto di partenza, ho provato a smanettarci sopra ieri eliminando la parte di post, utilizzando solo la parte Get , purtroppo ricevo sempre l'errore -403.
Posto qui sotto il Codice originale messo a disposizione da Cosm. Se qualcuno ha qualche idea.
P.S. il valore = 2777 l'ho messo io per testarlo.
Grazie
R.

/**

  • Cosm Arduino sensor client example.
  • This sketch demonstrates connecting an Arduino to Cosm (https://cosm.com),
  • using the new Arduino library to send and receive data.
  • Requirements
    • Arduino with Ethernet shield or Arduino Ethernet (board must use the
  • Wiznet Ethernet chipset)
    • Arduino software with version >= 1.0
  • Optional
    • An analog sensor connected to pin 2 (note we can still read a value from
  • the pin without this)
  • Created 8th January, 2013 using code written by Adrian McEwen with
  • modifications by Sam Mulube
  • Full tutorial available here: https://cosm.com/docs/quickstart/arduino.html
  • This code is in the public domain.
