title: Light sensor gauge
body: <p><strong>INTRODUCTION</strong></p>
  
  <p>For my job, I need to use a Light sensor for certain aplication. As I'm learning android, I decided to create a simple app that reads light sensor's values an shows it.</p>
  
  <p><strong>CONCERN</strong></p>
  
  <p>I know how to read light sensor's values and I'm actualy doing it. What I need is to create a gauge that represents these values. Something like this:</p>

  <p>Being the lower limit 0, and higher limit something like 30000lx (my mobile can read up to 60000lx but I think that 30000lx is enough).</p>
  
  <p>To do this, I started a tutorial from <a href="http://mindtherobot.com/blog/272/android-custom-ui-making-a-vintage-thermometer/" rel="nofollow noreferrer">here</a>. But I'm not able to adapt the temperature values to light values and redesing the scale, as as you can see on the picture, there are numbers floating, I don't get to put values, the hand doesn't appear, etc.</p>

  <p>So, I would appreciate a lot If someone could help me adapting the code from this tutorial, providing me any example or link, or anything that could help me to finish the app.</p>
