Hello, I'm trying to build a voltage sensor to trigger a speaker when my accelerometer reaches a certain angle. I'm still only in my basic electric circuits class and we're just getting into Kirchoffs laws and the like. I do have a bit of digital background with logic gates though.
My accelerometer outputs a 0 to 3.3v depending on it's angle. I just need an adjustable circuit, preferably using a resistor for the adjustment, that triggers a speaker when it's within a certain voltage range.
Say 1.6v to 1.8v I need the speaker to sound.
I would really appreciate the help guys! This forum has been very helpful in the past and I haven't been disappointed yet.
Thanks!
Also any notes on filtering caps a decoupling caps to clean up the signal would be helpful.
