title: Arduino error: expected primary-expression before '.' token
body: <p>I received a error from Arduino. And i'm very new into this kind of coding. (C)
  So, i received my first error on the IDE. But i have no idea how to fix it. I checked google, but nothing seems to work.</p>
  
  <p>I bought a LED&amp;Key chip for Arduino Mega. With the libary. I added the libary, and the functions are working. But, when i want to make my own code from scratch.. I received the error:</p>
  
  <pre><code>error: expected primary-expression before '.' token
  </code></pre>
  
  <p>And i have no idea how to fix it? And why?</p>
  
  <p>This is my code:</p>
  
  <pre><code>#include &lt;InvertedTM1638.h&gt;
  #include &lt;TM1638.h&gt;
  #include &lt;TM1640.h&gt;
  #include &lt;TM16XX.h&gt;
  #include &lt;TM16XXFonts.h&gt;
  
  #define module
  
  TM1638 modules[] = {
      TM1638(8, 9, 7),
      TM1638(8, 9, 6),
      TM1638(8, 9, 5),
      TM1638(8, 9, 4)
  };
  
  void setup() {
  
      module.setDisplayToHexNumber(0x0a1a, 1);
      module.setLED(TM1638_COLOR_GREEN, 0);
  
  }
  
  void loop() {
  
  
  }
  </code></pre>
  
  <p>Can i anyone tell me what is my fault? So i can keep up and starting with Coding for arduino!</p>
  
  <p>Thanks!</p>
