The Pibrella HAT gave us a simple way of programming the GPIO, however, the ultimate goal of Raspberry Pi projects is to create a customized working circuit. We will now take the steps to design our circuit, and then create the circuit using a breadboard.
The first step is to design our circuit on the computer.
Fritzing is a free circuit design software available for Windows, macOS, and Linux. There is a version in the Raspberry Pi store that we will install on our Raspberry Pi:
- From the
Application Menu
, choosePreferences
|Add / Remove Software
. In theSearch
box, type inFritzing
:
- Select all three boxes and click on
Apply
, and thenOK
. After installation, you should be able to load Fritzing fromApplication Menu

|Fritzing
. - Click on the
Breadboard
tab to access the breadboard design screen. A full size breadboard dominates the middle of the screen. We will make it smaller as our circuit is small and simple.
- Click on the breadboard. In the
Inspector...
