Hello All, I managed to get started with Blynk however Im stuck with some basic scripts for the NeoPixel Strips.
I can get most static functions like on and off and change to all red or all blue working but when I try to use some of the “strandtest” samples like Rainbow or ColorWipe its a no go.
What I would like is to have a toggle button on the app turn on and off say the “rainbow” affect or other type off effect etc.
Below is my script, Im new to both Blynk and Arduino so please be gentle if my Script is messy…
Thank you very much for anyones input…
