I'm trying to set up a circuit with an Arduino Uno, 2 potentiometers and an ADXL335 accelerometer. All are separate analog inputs that are completely unrelated to one another, but my question regards the voltage. With the ADXL335, I can only use the 3.3V slot on the Arduino.
Right now, I have the two potentiometers hooked up in a circuit that is connected to the 5V slot. I have this part of my project tested and working correctly.
Could I just connect the positive wire from this circuit to the positive of the ADXL335 and then run a wire to the 3.3V slot? Or, does the ADXL335 need to be on its own connected to the 3.3V and just have its GND wire connected to the potentiometer circuit?
Hopefully that made sense to someone out there. I can try and take some photos to better describe what I'm talking about if clarification is necessary.
