I want to amplify the output from my accelerometer
so that small changes in output voltage from the
1.6V "static" state would be amplified. So, for example,
if the voltage increases to 1.8 (delta=+.2V)
because of a small acceleration, I would amplify that
voltage change by a gain of say, 5, so that this same
acceleration would result in an output voltage of
2.6 (.2 X 5 = 1.0, 1.6 + 1.0 = 2.6). This output
would be fed into my Arduino Analog input so that I
can detect very small accelerations. Does anyone know
how to make an op-amp circuit that will accomplish this?
