Want to get better at coding Elixir? Write a hardware project with Nerves. As
you build this binary clock, you'll build in resiliency using OTP, the same
libraries powering many commercial phone switches. You'll attack complexity
the way the experts do, using a layered approach. You'll sharpen your
debugging skills by taking small, easily verified steps toward your goal. When
you're done, you'll have a working binary clock and a good appreciation of the
work that goes into a hardware system. You'll also be able to apply that
understanding to every new line of Elixir you write.
Combining software with hardware can be frustrating, but you can become
proficient in no time by taking a simple, logical approach. Blinking a single
LED is the traditional "hello-world" of embedded systems. Building your own
binary clock is the logical next step. It blinks groupings of LEDs based on
the system time. This guide walks you through a working project using the
techniques used by experts who build software for hardware every day.
This common sense project moves forward in tiny, logical steps. As you
progress, you can verify each step before moving on to the next. You don't
have to be a Nerves novice to benefit from this project. Become a better
Elixir programmer as you build your own desktop showpiece. With a layered
approach to software design, you'll learn to control the complexity of your
programs the way the experts do by focusing on one small slice of your system
at a time.
When you're done, you'll have your own binary clock, and also more of the
tools you need to design and build your own Nerves and Elixir projects. You'll
also be a better programmer with a deeper appreciation of layering techniques
for controlling complexity.
What You Need:
This project is for Elixir developers who want to get started with Nerves, or
improve their skills. The project is designed for Elixir 1.11 and Nerves 1.7,
but later versions will probably work as well with slight modifications. The
project uses a Raspberry Pi zero with a set of components. With slight
modifications, you can make this book work with other components as well.
