Inputs
- GND – This is where you connect the low side of the voltage you are measuring. Caution! : This is the same electrical point as your Arduino ground.
- VCC: The is where you connect the high side of the voltage you are measuring
Outputs
- S: This connects to your Arduino analog input.
- – (or minus): This connects to your Arduino ground.
- : This is not connected. It does absolutely nothing.
