Today we are going to look at the somewhat mundane but absolutely essential subject of supplying power for your electronic projects. 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.

@cschmitz 5 років тому

Thanks for making this video. This gives a lot of clarity to a topic I was having a hard time fully wrapping my head around. As a future topic would you consider explaining when and why you would add certain components into a circuit? For example, at one point in the video you mention that you need electrolytic capacitors for the 78XX voltage regulators, but you say there's no specific size you need and give the size you tend to use. In these cases how do you know that the size doesn't completely matter and what makes you choose the 2.2 micro ferret capacitor? When would the capacitor value matter? Stuff like that. I ask because I feel like I can find lots of explanations on what the components are, but it's a bit harder to find good/clear explanations of when and why to use them. Thanks again. Your videos are a fantastic help in understanding electronics. I appreciate the care and effort you put into them! :)

@dansquires2713 5 років тому

Great question.

@BloggerSWF 5 років тому

You can find this specific information at component Datasheets. Look for LM 317 Datasheet. That kind of capacitor do not influence in stability, it only improveh some noise safe, i.e, transient response. You are working with DC power, but you cannot delivery any fluctuations as spikes to microprocessor, it could generate a bad ghost instruction in the processor or even fry it.

@chifdagrif5105 5 років тому

He added them for decoupling. www.thebox.myzen.co.uk/Tutorial/De-coupling.html

@baruchben-david4196 5 років тому

The electrolytic caps are used to reduce AC voltage that may pass through the regulator. The exact size isn't too important, as long as it's big enough. So 2.2 microfarads is fine, but sometimes bigger would also work. It would be helpful to you to learn how to read schematic diagrams, and to get the diagrams that show how to use the devices you are using. Without that, you won't really understand what you are doing.

@somedude2492 5 років тому

The capacitors are to filter the in and out of the regulator, so you don't have spikes. The capacity depends on how big the spikes are and how many of them you have. The larger the spike, the more farads you'll need.

@geoffbirkinshaw8466 5 років тому

This is an excellent comprehensive presentation on what is available nowadays for voltage regulation. I learned my electronics in the 70s when we built voltage regulators from discrete components, transistors, zeners, op amps and even vacuum tubes in some cases. By doing this we learned how they work, but I have an uneasy feeling that modern enthusiasts know little of the internal workings of a chip or module with three or more connections to them and so would just replace it with new. I grant that it makes life easier than poking around diagnosing a faulty component on a circuit board but isn't that the point of learning about electronics. As an extreme example, why use an Arduino to flash a couple of LEDs when the person programming it has never heard of, or may not understand the workings of a simple two transistor astable circuit to do the same job.

@byoumina942 Рік тому

As an extreme answer, for the same reason that you built voltage regulators from discrete components and did not have to build the components first in order to use them in your voltage regulator project. That's the whole point of technology.

@boonedockjourneyman7979 4 роки тому

I just discovered this fantastic channel. You are filling a void in the UKposts EE world. Clear, directed and technically correct information. No ranting, bogus "tear downs" of cheap trinkets or racing to the bottom by trying to be some sort electro-comedian. As a career teacher at the post graduate level, now retired and teaching young people as a volunteer, I am worried about the near complete collapse of technically accurate education. Plug and play Arduinos, "robots" and drones have captured young minds but the suppliers of these toys are doing nothing to help new people find a future in the field. They are producing a generation of people who have no understanding beyond what color wire to plug in. I hope you keep up the first class content and resist the UKposts sponsor and product advertising gravity that has wrecked most channels.

I made this mistake early on and ended up blowing my buck convertors or getting erratic performance (brown outs). Your channel is like going to the robot school I never had!
