Every time I click the block all 25 values are send. Would it be possible to send a single value after I choose a color? So not when I click the block but after choosing a single color?
Not with colour inputs! This only works for text editing. Edit: And Boolean slots.
@petermathijssen you could try something like this (hello block added to indicate that the balloon is updated only when the input is, and the "has changed?" block is found in "Events" library):
I tried a small sample. It is working. The colors on the LED are changing live. To bad I have to use a forever block around it. Learned again something new.
