ARDUINO PROTO SHIELD
Can't see the forest for the trees? Yeah, it is
kind of hard to follow
these Workshops month
after month without an
occasional step back to
look at where we've been
and where we're going.
Back in the August
2012 Nuts & Volts, I
began a four part series
on Fritzing (Workshops
49-52). Then — still using
Fritzing — I introduced
the Arduino proto shield
in December 2012.

Now, at Workshop 57, we are at Part 4 of
the proto shield alarm clock series — this time
mainly discussing software. Believe it or not,
these nine Workshops are all related. What we
have here is a series that could have been titled
Arduino Fritzing Prototype to Production.
What we have done is to learn how to use
the Arduino and Fritzing to take a concept from
the first stages: a breadboard design, through a
PCB (printed circuit board) prototype, to a
production PCB. We've used an Arduino alarm
clock as the demonstration project around
which to hang the entire prototype to
So, naturally along the way, it got a bit
confusing as to what we were really doing.
Were we learning how to use Fritzing or learning
to use the proto shield, or learning to design an
The answer is yes — we were doing all of
that. Don't worry, however, we are coming to
the end of the tale of how to use Fritzing to take
an Arduino design from prototype to production
— and don’t forget, we've also learned a lot
about computer based alarm clocks.
I assure you the leaves fit the trees that fit
the forest that we are trudging through. So, if
while following me I moved a branch out of my
way, then let it go and it smacked you in the
face — sorry about that. Next time, you can lead
