I installed a circuit amplifier to my breadboard, to amplify the sound of my buzzer. I used a 9v battery as the power source. I connected it to the positive and negative line. The negative line is connected to ground.
The issue is I have a vibration sensor that can only withstand 3.3v to 5v.
Is there any way to test out whether or not the sensor would work? Without shortcircuiting it?
