This project contains various scripts for controlling Hue lights from a Raspberry Pi.

There are a number of testing scripts in the "experiments" directory, but the primary project contains code for a Raspberry-Pi based Hue Light controller. It consists of 3 buttons and a knob.

We use the Raspberry Pi B+ as the central controller. The GPIO has the following pinout:

Here is the schematic for the controller:

The prototype can be put together on a simple PiHat:

Here is the front:

And the Back:

The 3 buttons are:

• a large square LED which serves as the main button
• a red button which is the "back" button
• a blue button which is the "forward" button

The primary functions of the button are triggered with a "short press"

These are:

• Square button: toggle lights on or off
• Red Button: Switch to the previous scene
• Blue Button: Switch to the next scene

A long press will trigger a secondary functinon. The secondary functions are:

• Square button: Dump state to log
• Red Button: Delete the current scene
• Blue Button: Save the current scene

Additionally, a knob is used to dim the lights. An led is used to indicate that the lights are in the "on" state.
