&lt;p&gt;Then your teacher clearly thinks that you should be able to do this - if not, you should be talking to your teacher!&lt;/p&gt;

&lt;p&gt;So what does the program actually do?&lt;/p&gt;
&lt;p&gt;Before doing the SOS pattern, have you done a basic blinky which just&amp;nbsp;toggles the led on &amp;amp; off continuously?&lt;/p&gt;
&lt;p&gt;What debugging have you done to find the problem(s) with your code?&lt;/p&gt;
