The first step is to set up a Raspberry Pi with a headless version of Raspbian and enable SSH access. These prefixes are not meant to be typed and only serve as a reminder of which machine we should be logged into at that point. Note: terminal commands may be prefixed by a localmachine:~$ or pi:~$ prompt in parts where it may be unclear which machine we are logged into. If you already have access (either remotely, or via a desktop environment) to a Raspberry Pi, you can skip ahead to the Setting Up Your Development Environment section. There are many kits available on Amazon for under $20. 9 - 1k resistors (anything over 100Ω should be fine).9 - LEDs (preferably multicolored: 3xR, 1xG, 2xB, 3xY in this example).Writing a simple Python program to control the GPIO pins of the Pi to turn LEDs on/off.Setting up and connecting a breadboard circuit with LEDs to the Pi.Setting up a Python development environment on a Raspberry Pi.Configuring remote access to a Raspberry Pi via SSH.Setting Up Your Development Environment.

In this project we’ll just be turning on a few LEDs, but the main concepts covered here could easily be extended to trigger more complex events.
