I swapped the ColourSense (http://gadgeteering.net/module/ghi-colorsense) module for a triple slider (http://gadgeteering.net/module/soldermonkey-triple-slider-module).
[UPDATE] RGB Slider – LED Strip with RGB slider
As requested here is an example of my colour sensor in continuous mode setting the colours of the LED strip. The code below uses the tweaks shown in these two posts:
Last post I was looking at the individually addressable LEDs and used the ‘ColorSense’ module to detect colours. (But did not get very good results)
This post addresses the issues with the colour sensor.
[UPDATE]: Sarah and Jan emailed me to mention that the 10A@5v power supply is a bit of an overkill. I agree but this is the recommendation from GHI. When I tested my strip on full power it was under 3A@5v . Jan claims his is around 2.6A@5v . This does not account for peak current draw, so you may hit issues, but perhaps the full 10A is a bit much.
[UPDATE: C# and VB solutions are at the end, the first part is ONLY an explanation. You do not need to follow the steps, just look at the code at the very end if you are after a fix. ]
I was asked to show the source behind the example shown in the .NET Gadgeteer LED Matrix blog post.
(as is, no warranty, and I am sure there are bugs etc blah blah)
