title: Arduino HTTPClient not working
body: <p>I have an Arduino with an Ethernet shield.</p>
  
  <p>I have the httpclient library, and I am trying to run the PachubeClient example.</p>
  
  <p>When I compile, it gives me many errors:</p>
  
  <pre><code>PachubeClient.cpp:25:25: error: Credentials.h: No such file or directory
  PachubeClient.cpp: In function 'void setup()':
  PachubeClient:47: error: 'ssid' was not declared in this scope
  PachubeClient:47: error: 'passphrase' was not declared in this scope
  PachubeClient:55: error: a function-definition is not allowed here before '{' token
  PachubeClient:95: error: expected `}' at end of input
  </code></pre>
  
  <p>Why?</p>
