Then its internal wiring will look like this:
Notice that the numbered rows are all connected from a, b, c, d to e, but not across the canal over to f-g-h-i-j, on the other side of the canal its another lane.
This is how we place the raspberry cobbler on the breadboard:
When the cobbler is placed like this then each pin on the cobbler gets its own lane that is important. If each pin was not getting its own lane then you would almost certainly damage your Raspberry PI.
