We do need to update avrdude, which might help. In the meantime, however,
you might do the following:

1. Press "Upload" (or whatever icon we use)
2. Hit reset on your board just before the upload.
3. Profit!

When dealing with serial, I find that sometimes the Arduino misses things,
because it comes to life and starts doing things with the serial port.
Resetting the PC... well, I use a Mac, so I face different issues at
different times.

Underneath, we're using the same tools as the Arduino IDE, so there
shouldn't be anything too special/different there. At some point, let us
know what those errors are specifically, in case there's anything we can do.

Windows does not like you. (Read: I have no idea.)

I was kidding about not reading in. You're welcome to ask any and all
questions about what you find. It is certainly the case that we might be
able to usefully expose more in Plumbing... that I don't doubt. That said,
because of how occam #includes work, our "libraries" are not really
"blessed" entities. For example, you could start working on
"libjames.module", put it in the same directory as your code, and do

#include "libjames.module"

and it will be pulled in. Further, the include is the same as copy-pasting
the code into the file it is being sourced from. So, really, all of the
code in the "library" folder is only special because someone other than you
wrote it. (If that makes it special.)


W.R.T. your code:

If you are actually using a PIR module, you might also look at

https://github.com/jadudm/Paper-ES-Sensor

where I use the Modern Device PIR sensor. In that context, I think I was
using it in an interrupt-driven mode.

https://github.com/jadudm/Paper-ES-Sensor/blob/master/pir.module

and

https://github.com/jadudm/Paper-ES-Sensor/blob/master/just-pir.occ

might be of interest.

Or, if I'm completely wrong, nevermind. :)

Cheers,
