Prototyping Project (Clock)
In this chapter, we will build what can only be seen as a grossly over-engineered LED digital clock.
We will be using a Raspberry Pi, Adafruit’s Cobbler lead, a breadboard, and a four-digit LED display
(see Figure 10-1).

In the first phase of the design, the project will just display the time. However, a second phase
extends the project by adding a push button that, when pressed, switches the display mode between
displaying hours/minutes, seconds, and the date.
What You Need
To build this project, you will need the following parts. Suggested part suppliers are listed, but you
can also find these parts elsewhere on the Internet.
