To solve this problem, he created something called the Raspberry Leaf (shown in
Figure 1-6
). The Raspberry Leaf is a perfectly sized and scaled diagram of the Rasp-
berry Pi GPIO pins, with the BCM labels next to them.

Connect GPIO Pins to a Breadboard
HACK 15
A solderless breadboard is a helpful friend when building electronics
hacks, especially when you are prototyping or just testing out a device.
Let's hack a simple connector to our Raspberry Pi.
While you can simply connect your Raspberry Pi GPIO pins to devices via common
jumper wires, or solder wires directly between your add-on device and the GPIO pins,
it is almost always helpful to have a little more space to work. Enter our old reliable
friend, the solderless breadboard, shown in
Figure 1-7
. Even if you've never done an
electronics project before, you may have seen this fellow with rows and columns of
little holes in a rectangle of white plastic.
