I've attached an image of a LED wreath I built. It's built with 24 5 pixel strips around the wreath circle. I'd like to create a VU meter effect where the lights gradually sweep upwards from the 6 o'clock location up to the 12 o'clock position depending on the volume or waveform of the singers voice. The look I'm going for is that each 5 pixel strip needs to be the same at all times, and the wreath is mirrored so that the left and right sides are identical. The strip at the 6pm POSITION is shared between the two sides. So at the first quiet sound only the 6pm strip is lit up. At 50% volume the strips from 6 o'clock to 3 o'clock are lit up (and mirrored on the right side...so 6 o'clock to 9 o'clock is also lit up). At full volume the whole wreath is lit up. Does this make sense? I've been struggling trying to create this effect. Logically it's just 2 bars with 11 levels. I just cannot figure out how to tell it to light up 5 pixels at a time. I would think this could be called something like "Bar width"
Anyway can anyone tell me if this is possible and if so how to achieve this effect?
