Walter Needs a Mouth
February 18, 2011
We did this once with walter's old "eyes", now another round of brainstorming with his "mouth".
Walter needs a mouth. In the past I have used the "picaxe sound detector circuit" modified a bit, going to a few blue LEDs. As a track was played (assume the track is speech) the leds would blink and change intensity according to the audio levels. This was ok, I guess... I think I might want to go to a "led bar-graph chip" with say, 8 to 10 segments. As he speaks, the bars could be lit --from the center -->out and with more bars showing as audio levels increase. I dunno.
Has anyone played with any "audio display" chips? EQ's and the like? I know there are some drivers out there that will probably do exactly what I want to do, I just have never played with them.
