I have made a circuit that produces a 3.3V high when its active and 0V when it is off.
Now I would like to extend it with a speaker that plays some sort of alarm (although it shouldn't be too intrusive, but clearly understandable) that I wan't to activate with said circuit. So it plays some sort of tune or alarm for as long as the signal is high.
So what would be a simple way to create a triggerable alarm/tune without the need for a computer?
Ideal would be some sort of chip with preprogrammed music or something on it that I could just hook up to a speaker and that could simply connect to the output of the circuit.
I have looked for something like that but it doesn't seam to exist, they always require a computer or a raspberry pi to set the samples.
And just connecting a speaker to the signal outright just creates an irritating tone.
