Hi I need some help how to do this if possible. I want to make some kind of sound sensor that will pickup the sound of a small steel ball hitting a steel plate. Some times the ball will hit soft (low sound) and some times it will hit hard (high sound). I need to trigger a LED that will come on for 15-60 seconds. I can handle the LED part of the circuit using a 555 timer.
Now for the hard part. I need sensor A to not be triggered by a sound that is meant for sensor B, that might be 3-6 feet away. If I can do this there may be up to 20 sensors, but no closer than 3-6 feet apart. Would I be able to use something like this https://www.jameco.com/webapp/wcs/s...toreId=10001&catalogId=10001&productId=121252 and put it in a tube to make it more directional? The sensor can be two, to 12 inches away on the back side of the steel, or three to five feet in front of the steel. In front is the better of the two for mounting the LED.
Any Ideas? Keep in mind I have only been playing with electronics for a few months, so I don’t have much of a clue. But I can make a LED flash using a 555 timer.
