Delete the proto shield and mini breadboard, which
will leave you with the components shown in Figure 13.
Now, do a block copy of these components and open the
Fritzingduino project. Paste the components on the
breadboard as shown in Figure 14. You'll need
to delete and/or move some of the wires, then
add the CR1220 battery component as shown
in Figure 15. Note the following when wiring
• Digital pin 9 is PB1 pin 15 on the
• SCL is PC5 pin 28
• SDA is PC4 pin 27
You'll get a schematic shown in Figure 16
(of course, you'll need to move the
connections around a bit to get this exact
image). The resulting breadboard view is
shown back in Figure 1. Now you have
combined a minimal Arduino clone with an alarm
clock design on a single PCB. Plus, you’ve developed
some major prototyping skills in the process.

GO FORTH AND CHANGE
Congratulations! You have learned how to use
Fritzing with the Arduino to do designs from the
prototype stage to production. You can now take
that itchy idea that makes you want to scratch your
brain and build it on an Arduino proto shield
breadboard for preliminary testing. You can then port
that design to an Arduino proto shield PCB for a more
robust platform. If you want to make more than one,
you can then design a PCB that incorporates your idea
with the minimum parts for an Arduino compliant
clone — all on a single PCB that you can get made
through any of the many PCB houses.
When your Kickstarter project gets funded and
you get rich off your brain itch, be sure and
remember those of us who helped you along the
