Accelerometer sensing

view story

http://forum.allaboutcircuits.com – 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 foru (Embedded)
