More ambitious debug listings are also possible.
As you might have guessed from the eight checkboxes
along the bottom of the debug window, you can
eavesdrop on a subset or essentially all Arduino/MakerPlot
communication messages. This is an immense help in
debugging the type of errors that might arise from
development efforts in this and similar projects. Typical
output would be similar to that shown in Figure 13.
Perhaps something that displays an ASCII string in hex
It is also possible to limit the display of debug
messages to only those containing a target text string
entered into the filter text box at the
bottom of the window (not visible in

This simple project actually
ignores a lot of MakerPlot’s
capability. It is aimed at the reader
who is interested in how Arduino
code and MakerPlot functionality can
interact, and what the result might
look like in the context of a simple
18 AWG zip cord rated 300V,
2" controller board. Resettable
to zero. Requires two momentary pushbutton switches and
9 Vac power (see our CAT# ACTX-940).

If you are serious about applying
these techniques to future
microcontroller projects, the next
step is to spend some time with the
rather hefty MakerPlot User’s Guide!
