I haven't done anything with electronics for a few years, forgotten most of the stuff I've learned, so I'm having trouble now figuring something out:
I have a simple metronome that beeps the BPM (Tempo beats per minute). Here is a screen-shot of how 96 BPM looks on the scope:
So the beeps are short sine/square waves about 2.2 Voltage, positive and negative.
I want to build a circuit that will close a switch on/off (of another circuit) according to the tempo beeped by the metronome.
Can you guys recommend a simple schematic, either with a relay or with transistor, or maybe it could be done by using a opto-coupler?
thanks in advance
