This project aims to take in HDMI source and output coordinates or in some way light up a programmable LED strip with the correct lighting effect based on the HDMI screen.

Objective

• [x] To have a basic testing facility for the above. This includes:
• [x] Generateable "screen" that plots out and is a length x height rectangle made up of x x y pixels of the appropriate size.
• [x] Generateable "strip" that plots around the edge of the above screen a configurable number of n LED's (colored dots).
• [x] The color of the dots will be in some way selected from the colour of the pixels around it. This could be by:
• [x] Nearest neighbour (match the colour of the nearest pixel).
• [x] N-nearest neighbour (average the colours of the nearest N pixels).

Future

In the future the following are necessary steps to incorporate this into a real system.

• [ ] Incorporate and extract the real pixels from a video feed.
• [ ] Incorporate a real LED strip and allow for adjustment of the locations to align the test with the real screen.
• [ ] Incorporate this into an embedded device such as a Raspberry PI to allow this to happen in proximity to the screen (Likely performance considerations to do real-time).

In the future the following are attractive steps to make the real system more functional.

• [ ] More sophisticated mechanisms for determining the light that an LED ought to emit (bright or dark, smooth large color differences between frames, etc.)

Examples

On an arbitrary screen made up of 900 pixels (30x30) with 100 LED's using the nearest neighbour to determine LED colour.

On an arbitrary screen made up of 900 pixels (30x30) with 100 LED's using the average of the 50 nearest neighbours to determine LED colour.
