In that case you can leave it open, connect to the negative terminal, or connect it to the positive terminal to make a negative-voltage supply. Or, you could use two of these supplies to make a dual (positive and negative) supply. If you leave it open, the negative terminal could be used as an isolated low-voltage ground for your Arduino …
power supply
The way I understand it, the power supply sets up a potential difference between the positive and negative terminals. The ground terminal is simply connected to earth ground. It seems to be common to connect negative and ground, if you want a positive reference above ground.

What happens if you disconnect the positive terminal first?
As long as you don''t touch the battery positive terminal at the same time you will be OK and since the battery positive terminal usually has a red cover on it there is little risk. Once the battery negative is disconnected, accidentally touching the battery positive to the cars bodywork using a tool is no longer dangerous.
Solved 1. Batteries are a DC power supply, having a positive
1. Batteries are a DC power supply, having a positive terminal and a negative terminal. If a battery were hooked up in a circuit, would the electrons travel from the positive terminal to the negative terminal or vice versa? 2. Wiring an LED to a circuit requires the positive leg of the diode to be connected to the positive terminal of a battery.
21.2 Electromotive Force: Terminal Voltage
The lead-acid battery used in cars and other vehicles is one of the most common types. A single cell (one of six) of this battery is seen in Figure 21.10. The cathode (positive) terminal of the cell is connected to a lead oxide plate, while the anode (negative) terminal is connected to a lead plate.
Do you connect negative or positive first?
"Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Positive Or Negative First When Connecting A Battery: Solved! All car batteries have two terminals; the positive and the negative terminal. Knowing which one to connect first and last between the two can …
Should I put the fuse on the negative battery terminal?
If electrons, which form the electrical current and have a negative charge, do move from the negative battery terminal to the positive terminal, does this mean that the fuse should be on the negative battery side and not the positive terminal?
Why is the ground pin always connected to the "negative" power supply?
Every piece of electronics whether it be a microprocessor or LCD screen always has a positive power supply and a ground pin. The positive power supply or VDD is clearly where you supply something like 5 volts. It would be like taking a 5 volt battery and connecting the positive end with a wire to the VDD pin. But the ground pin is always ...
