Trust me, this stuff is important! Electronic devices typically require either 5 or 3.3 volts, sometimes both. Other common voltage requirements include 6 and 12 volts for motors and displays. Some complex designs (ie. a robot) require several different supplies with different current capabilities. When you build your latest robot or IoT device you’ll need to consider how you'll supply these voltages in the real world. On the workbench you can use a bench power supply if you have one, a USB adapter, or even the USB port on a computer (just like with the Arduino). But when your creation needs to exist on its own with a line-powered or battery power supply you’ll need to figure out how to get all of those voltages delivered to your components, preferably easily and inexpensively. I have nine, yes nine methods of doing exactly that. Today I’ll show you a number of different voltage regulators and converters ranging from the classic 7805 3-pin voltage regulator to a tiny device that can supply a steady 5 volts even when your battery is about to die. Check out the following Table of Contents to skip ahead to the power supply solution of your choice. Or just sit back and enjoy the show.

As with all of my videos, there is an article where you will find more details regarding all of the voltage regulators, buck converters, boost converters, and buck-boost converters mentioned here. Now go power something up!
