Hello all,
I am in a circuits class now and we are doing our end of the year project. I have decided that I want to do some sort of circuit that counts things. For the actually counting portion of the circuit I am just busting open a cheap little calculator and connecting two leads to the = button so that if you type some numeral and operator before then you can just hit it and it increments this count.
In terms of what I want to count, I was thinking of adding some type of speaker to the circuit so that every time I clap, snap, yell, whatever it increments this circuit, but I have no idea how to do this. I am pretty sure that I will have to have some sort of transistor hooked up as an amplifier to the speaker so that it will create a large enough voltage to actually complete the circuit, but I have no idea besides that.
Thanks so much for any information at all.
