@hugobarauna and I (Alex Koutmos) have been hard at work on writing a book on Nerves that takes you from simply blinking LEDs to building LiveView powered kiosks (and everything in between).
You’ll be building projects like:
- A Morse code translator
- A reaction time tester
- An Etch A Sketch that renders in Livebook using knobs
- Upgrading the Etch A Sketch to use a joy stick
- Rending CPU temperature from the Raspberry Pi in LiveBook using VegaLite (you’ll also write a simple stress test to get the CPU hot
) - A simple weather report/clock using a 20x04 LCD display
- Displaying of accelerometer data using OLED displays
- Interacting with accelerometer data using a LiveView kiosk
By the end of the book, you will have built a wide a array of projects and should be more than comfortable tackling some of your own Nerves projects!
Part 1: Rapid Prototyping Nerves Using Livebook
- Getting Started With Livebook
- Build a Morse Code Translator
- Build a Traffic Light Simulator
- Build a Reaction Time Game
- Building the Etch A Sketch Circuit
- Programming the Etch A Sketch
Part 2: Building Custom Nerves Firmwares
- Build a Custom Nerves Firmware
- Optimizing Your WorkflowC
- Interfacing With I²C Hardware
- Creating a Nerves Kiosk
Appendices
- Basics of Electricity
- Selecting Resistors
- Using a Breadboard

Looks interesting. What is the expected timeline for the book to be completed?

The goal is to have the book edited and completed by mid 2026.

Thanks! Here is a screenshot of the “What you will need” section:
This is subject to change as the projects are tweaked here and there during Beta. That said I don’t imagine it’ll change much.
Specifically regarding the Raspberry Pi, the wiring diagrams in the book are based on the Raspberry Pi 5 like so:
But if memory serves me correctly, any Raspberry Pi that has the 40 pin header should work (Raspberry 2+) as they standardized on the pins. So you have some flexibility with regards to what hardware you use.

Apologies if my previous comment was unclear. I meant anything with higher specs than the Pi Zero 2 W, including the Pi Zero 2 W. So I would suggest using one of the following to complete the projects within the book (also depending on what you plan on doing with the Pi long term):
Given that the Livebook distribution of Nerves will consume about 100MB of memory at idle, you have about 400MB of memory left if you go with the cheapest option in the list (that being the Pi Zero 2 W which has 512MB of memory).

I also forgot to add that anyone attending the ElixirConf Nerves training in Sept also gets this book for free!!
