Hey guys,
So I have a few push buttons set up each one of them responsible for a different light effect. The idea is that when you push the button the effect will start, however if you push another button, it should erase the effect from the first button (even tho it hasn’t traversed through the whole LED strip) and just immediately start the next effect. (or if you press the same button twice in the span of a few seconds, it should again break wherever it has reached with the first press and start from the beginning). As of right now, the effects are working just fine with the buttons, the only problem is that the system always wait for the effect to go over all LEDs in the strip and only after that’s done, it triggers the effect again. Do you have an idea of how this can be solved?
I’m sorry, the code is a bit of a mess
