Hello I am looking to incorporate a few sound sensors into my project but had a question before I got started.
First, the particular model of sensor I am using does not appear to be analog, it only has three pins (vcc, gnd, and out), but I need to use three different sensors (one for left, one for right, and one for center) to determine which direction a servo should turn. But, being that the sensors are digital, I need to do a digital to analog conversion so as not to get a false positive on the other two sensors when one is triggered.
Sorry this is a bit of a basic question, but I suppose in short, how do I do a digital to analog conversion? I've down ADC, but I'm not sure how to do the opposite. Also, being that the sensors are digital by default, would digital to analog even work (like measuring volume), or would it still always output at a higher signal? Thanks!
