title: How to split a string using a specific delimiter in Arduino?
body: <p>I have a String variable and I want to extract the three substrings separeted by ; to three string variables.</p>
  
  <pre><code>String application_command = "{10,12; 4,5; 2}";
  </code></pre>
  
  <p>I cannot use substring method because this string can be like any of the following or similar patterns also.</p>
  
  <pre><code>String application_command = "{10,12,13,9,1; 4,5; 2}"
  
  String application_command = "{7; 1,2,14; 1}"
  </code></pre>
  
  <p>The only thing that is common in these patterns is there are three sections separated by ;.</p>
  
  <p>Any insight is much appreciated.
  Thank you</p>
