Creating signal with arduino Uno


I would like to creat a specific wave weft with arduino, it’s very difficult to explain this so maybe with a picture it’s simpler.

Do you have an idea?

Thank you very much


Please explain the purpose of this project. Background can give a lot of help in understanding what you want and saves us guessing only to find we have waisted our time on the wrong track.


How many steps? What triggers from one to the other, is it time. How many variable periods? What speed is this. Do you not mean a warp? Because a weft goes across and does not change but the warp lift will.

I think the code for blinking an LED in the demo Several Things at a Time could be adapted to to this.
