Is possible to include a IR color gradient for a LED?. I’m working with melexis MLX90621 16x4 IR temperature sensor but it’s very difficult to show it with the actual widgets.
Somehow making a widget display a gradient in IR is not likely to happen, or if it has already… well… we can not see it because it is in IR 
But perhaps I am not understanding your question (it happens)… Can you clarify what you are trying to do?
So I guess you’re looking for some way to give visual feedback about the ‘colour’ of the invisible IR led array?
How about using a gauge widget to give a representation of the IR colour? I guess you’re able to translate the current IR LED colour into a value that you can send to a gauge widget?
If you actually want to change the IR colour output you could use the zeRGBa widget?
Pete.
I looked closer at the post… this is a sensor… effectively a mini IR camera. Sorry, but there is no widget that will display the matrix output of this sensor. The closest you might get is the Video Widget, assuming you can get some other hardware to process the IR image and broadcast it as a video stream that the Video Widget can access.
