in Fritzing connected; and then
on the right, there’s a replicator
that is outputting tiny flying
submarines. This cute drawing
pretty much covers what the folks
at Fritzing think they are about
and although they have a long
way to go, they at least are

When I first opened Fritzing,
it came up in the breadboard view
shown in Figure 4. Let’s close the
breadboard welcome and move
the breadboard up and resize
the whole window as shown in
Now, in the parts window
open the core parts and scroll down to the ICs. Hmmm ... they
have a DS1302 (as shown in Figure 6), but we are using the

and DS1307 aren’t the same. So, let’s see if there is any help for
this problem. [NOTE: I found a better way to get the DS1307
