Setting up the circuit

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

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:

1. From the Application Menu, choose Preferences | Add / Remove Software. In the Search box, type in Fritzing:

2. Select all three boxes and click on Apply, and then OK. After installation, you should be able to load Fritzing...
