Hello everyone!
I'm modifying a strobe light trigger, in orden to fire it according to a music input. I've made some work, but I'm stuck on the 4th point.
1) The strobe light is just a cheap 12V chinese model, nothing interesting about that.
2) The lamp's trigger will be wired in series with a TRIAC, driven via optocoupler by the circuit.
3) Next part was the bandpass filter, to allow only low frecuencies to trigger the circuit. I've found a schematic (attached).
4) Now the bad part. I don't know a decent way to trigger the strober only when Low Frecuency signal reaches a determined Threshold (loudness).
I recurred to my old friend LM3915, using only one of its LED outputs (# 5). But is a waste of machine, I guess there is a better way!
On google I've found a microcontroller solution, but I have zero experience with them.
Is the solution some kind of comparator?
