We’Ll talk about all the different kinds of Arduino available, how much they are, what they’re capable of and which is suitable for your project. This is pretty much designed as a beginner’s guide for the sort of person who has just graduated from their starter kit or who hasn’t even bought an Arduino yet I’m, hoping to show you what kinds of Arduinos there are and what they’re best suited to. First up the uno with clones, costing as little as three dollars the uno, while not the first Arduino board, remains the most popular it’s. Also, the model you’ll find included with most starter kits it’s, the you know that sets the standard for upgrade shields boards, which can plug onto the top of Arduino to enhance functionality, add features, and they can often stack with each other. So you can add more and more of them about the size of a credit card. It has a full sized USB port and a DC barrel jack, accepting up to 12 volts DC. It has 14 digital io pins, five analog ones and runs off 5 volts. It can be powered either by the USB cable or by some external power through that barrel. Jack at the heart of the you know, is the atmega 328p, with 32 kilobits of program memory, which is pretty small by today’s standards and at some point you’ll probably want to upgrade to something bigger, but as a starter device is perfect. Really next up we have the mega 2 560 and this is basically an upgraded uno.

If you find yourself running out of Io, pins or memory, but you still want the form factor of the uno, then you can upgrade very easily to a mega. Shield’S can also fit on top of this in the same way that they do with the Arduino Uno. Although twice the price of the you know at about six dollars for a clone, the mega has 256 K of memory along with a whopping 53 digital io ports and 15 analog port. Like the you know, it has a sighs, USB port and DC for external power. So it’s really just useful when the uno just isn’t big enough. Next, we have a pro micro. This tiny, tiny little thing with clones available for about three dollars. Each the pro micro is both small and has the ability to become a USB human input device. Like a keyboard or mouse, it has a micro USB port on the side, it runs off five volts or 3.3 volts and, of course, it’s tiny, so it’s great for small projects, though this does leave you with a couple less IO pins to play with and like The uno, it only has 32 K of memory, there’s, also a pro mini and nano Arduino available, which is basically the same thing, but without the onboard USB controller I’m gon na skip right over these, because if you need them, you probably already know that and you’re Not really an Arduino beginner for beginners I’m definitely going to recommend the pro micro just because it has the built in USB controller and it can become a keyboard or Mouse and honestly there isn’t that much of a price difference so for beginners.

This is definitely the one I would recommend if you want the tiny form factor at this point. I also want to talk about a node MCU dev board, which is Arduino compatible amongst other things, so, while it isn’t actually an Arduino, you can use most of the Arduino code on it. Although you may need a couple of modifications available for as little as four dollars, each the node MCU board comes with a built in Wi Fi connection, which is incredibly powerful for Internet of Things. Projects that you might want to take on just a couple of lines of code and you have it connected to the Internet. The only downside to working with the node MCU board is that the pins run at 3.3, volts they’re, not 5, volt tolerant. So if you have a sensor which is outputting at 5, volts you’ll need to do some logic level, shifting to get the voltage down to 3 point 3 by the time you’ve graduated from your uno. In your starter kit, this probably won’t be a problem. Finally, we have the lilypad arduino, and this is a bit of a weird one – really it’s a 5 centimetres circular board and instead of pins or sockets, that you can push pins into it has pads, and these are designed to be sewn with conductive thread. So it’s really for wearable projects, the lily pad uses the same processor as the uno. So much of the code is portable, just upload it to this and it’ll work.

Fine, the only problem is the lily pad. Doesn’T come with a USB connection, so you need a separate FTDI breakout like this, which gives you a USB port, so you can plug in and program. If you buy the lily pad. 3 6 8 version you’ll find the pins are 5 volt, tolerant, so otherwise it’s exactly the same as working with an Arduino Uno. Lastly, I wanted to add a quick note about the new generation of non Atmel based boards. The Arduino unit, for instance, is a curious Linux, combined with Arduino, as well as Bluetooth and Wi Fi on the same board. These bear more resemblance to a Raspberry Pi, but with a whole lot less community support and a much bigger price tag. The Arduino unit is about 75. My advice just steer clear of these new boards, they’re simply overpriced for their intended Internet of Things. Applications you’d be much better off with a little node MCU dev board for 4 dollars or even consider a 35 Raspberry Pi. If you need that full Linux stack to play with so those are the board’s that, as a beginner, I think you’ll be most interested in or interested in upgrading to next after you’ve finished with your owner in most cases for simple prototyping, I still keep around a Bunch of simple who knows they get the job done, and they’re cheap and they’re easy to work with. If you need more space for code or more ports, then upgrade to a mega to 560.

If you’re ready to embed your project or if you want to make it really really small, then you can always consider a nano. But if you like, the small form factor and would also like to play around with something that can become a USB device, definitely consider the pro micro for wearables. The lilypad is a great option. You can sew straight onto it with conductive thread and finally for Internet of Things based projects. I really can’t recommend the node MCU enough, it’s so cheap to get something that will connect straight to Wi Fi in a couple of lines of code. So you can get something really cool working, really quickly, that’s it from me thank you for watching and for more weekly technology, tutorials reviews and giveaways from make use of com.
