Power Supply and Voltage Source

No electrical device will work without electric energy, that´s no-brainer, however, you need to supply the right voltage. That is something a voltage source can help you with.

To set the record straight, a voltage source does not actually supply the the energy itself (except for a battery), it rather converts the energy. Generally speaking, the input energy entering a voltage source equals the output energy (with some losse), while altering the ratio between voltage and current.

AC-DC power supplies use AC current as input voltage, mostly from the mains, and DC voltage as output. DC power connectors allow you to safely connect these power supplies to your devices. For higher voltages, you can use 12V power adapter, 24V power adapter or a 12V mains adapter.

LDO controllers, Step-Up Converters a Step-Down Converters operate only with DC voltage.

Batteries and accumulators store electrical energy in chemical reactions based on oxidation-reduction potential. In case you plan to use a battery such as Li-ION 18650 or 3.7V Li-ION battery, it's a good idea to also buy a dedicated charger and protection. Battery protection ensures safe operation and long life. For proper charging, use the guide on How to charge Li-ION batteries a how to properly charge a Li-POL battery.
