Build a Binary Clock with Elixir and Nerves »

Want to get better at coding Elixir? Attack complexity the way the experts do and sharpen your debugging skills by building a binary clock with Nerves. When you're done, you'll have 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.

Build a Binary Clock with Elixir and Nerves: Use Layering to Produce Better Embedded Systems

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.
