    Manually adjust output voltage?

    The output is coming from an accelerometer. The Accel is on a circuit board which is on a table. When the table is level, the Accel should output 2.5 VDC to the microcontroller. But circuit board doesn't sit level on the table, so I want to be able to adjust a Potentiometer to tell the...

    Manually adjust output voltage?

    crutschow - the output is going to a microcontroller so the current requirements are in the mA range. MrAl - the output will be constant, but for each circuit I make the voltage may be above or below what I want it to be (2.5VDC). CCD - the classic LM317 voltage regulator can bring my...

    Manually adjust output voltage?

    I am looking to manually adjust an output voltage to a get specific voltage. For example: the output voltage needs to be 2.5 VDC and my output may be 2.3 VDC or 2.8 VDC. I am looking for a way to manually adjust the voltage using a potentiometer (and possibly some op-amps). Any suggestions?
