<p>Okay, so we know it is happening in the handling
of the conditional. Run it twice. Once with the
test for maxDistance removed and once with the
test for equality removed. Also, add a print out
of <i>maxDistance</i>. Need to make sure it is
not being changed although the test with '200'
there should show it isn't. <br>
</p>
<p>If you get the same results I'm going to start
drinking. <br>
</p>
<p>Actually, I'll start wondering about the build
process. I'm not familiar with PlatformIO. The
Arduino IDE takes all the files, rearranges them,
and then compiles the resulting file. That's
unlike most C++ build systems. The "rearranging"
can lead to some strange issues. <br>
