Also, I'm not sure which, if any, of these three have this capability, but when I built a MIDI controller for my computer, I went with the Leonardo because it can be set to be recognised as a standalone USB device when plugged in.
2:47 I think you were mistaken Nano with Micro / Leonardo. Nano doesn't have netive USB, so its difficult to trigger keyobard, mouse withou a middleware
Thank you for sharing. I have a question. How do you supply power to multiple arduino NANOs using a usb portable charger without a multiple usb ports, or without getting a usb multiple ports? Weight is a factor for me. Is it possible to power chain the Nanos?
Hi Muhd, if I understand you correctly you want to power multiple Arduinos on one portable charger. Don't pin me on this, but I think you can make a female plug for your portage charger, which then is wired to the Vin pin and GND of all the Arduinos you want. However you have to make sure the portable charger provides enough power for all of them.
Hey, does anyone know If the mini usb host sheild is compatible with the arduino uno, and If it is can you please supply a link with how to connect them together, thanks in advance!
The ending was awesome. However as a non electronics person, I would like to know what parts were exactly taken out from each model so that the size was possible to reduce.
Good question! I don't know by heart but the form factor doesn't necessary mean that components are removed. For example the original UNO has a large chip. The is also an SMD (surface mounted device) variant is which is tremendously smaller.
a video suggested me to use arduino nano in a project but we are not able to get it for a reason but we do have arduino mini can we use it in our project kindly reply fast as the due date is near i am just a beginner
Thank you very much but I would like to point out that the comparison of the number of digital input-output pins is wrong. Uno has 13 indeed but Nano only has 14 and not 22. 22 is inclusive of the 8 Analog input pins too.
Hi, the description of this video contains links to the official Arduino website. For nano this is store.arduino.cc/arduino-nano which states "Digital I/O Pins: 22 (6 of which are PWM)" I guess they count analog pins as well.
@@BasonTech Every analog pin has the capability of being used as a digital pin. So in this case then the Uno and the pro mini would also have more digital pins. Next time use a comparison table of this kind of output in your conclusion; I was looking for that. Besided that: thanks very much for you good work Bas.
OK I am new to Arduino. If I am understanding this the units will perform the same functions. I need a unit that can accept up to 4 - 9 to 14 VDC inputs while controling up to 3 PWM outputs. So it seems that the ProMini may be the hot ticket for me on the final product. I have bought 2 UNO's and will use these for all the testing and design. Then I should be able to take the programs and dump them into the ProMini and it should work the same? Right?
Keep in mind there is a 8Mhz Pro Mini as well, where the UNO has a 16Mhz processor. So make sure you buy a 16Mhz Pro Mini, otherwise you have a twice as slow processor. Be aware that 14V will be too much, since the max is 12V. Your code is indeed the same, unless you use I2C pins, these might differ per Arduino model.

I'm looking for a really tiny arduino board for my first ever project since it has to fit inside of a gearknob. So far I've seen Teensy LC/Teensy 2.0/Pro micro. Any recommendations? I need it for 3 button switches only, so really tiny project. (1 NO button and 2 NC buttons, nothing else)
The is this tiny Arduino www.kickstarter.com/projects/melbel/pico-the-worlds-smallest-arduino-board The ATtiny85 is also very small tinkersphere.com/boards/706-attiny85-breakout-board.html Hope this helps 😃
Good video. Though the idea of shields is not unique. Intel used it on their boards 40 years ago. I used them and later made designs with piggyback cards on top of my main boards.
Question: if you are looking at code that was developed on the Uno, what changes do you have to make to run that code on the nano or the pro mini. If you want you can just answer between the Uno and the nano because I agree that the nano in most cases is better than the pro mini. Thank you very much for making your video it really helps a lot!
From the top of my mind Uno to Nano is not much of an issue. The Nano has more analog pins so the other way around could be an issue. Also am I not very sure if the SPI pins differ on both devices. So keep that in mind if your code uses SPI. A more hardware related issue could be that the Uno is 5V and you might happen to have a 3.3V nano. This could potentially raise errors if you are using components that require 5V. Hope this helps 😃
Thanks, very interesting. I saw a couple of inaccuracies, though. You count the analog pins in the Nano as digital too, but not on the other two boards. Analog pins can be used as digital in all boards, there should be more consistency there. Also, the Nano does not support Keyboard/Mouse emulation, it is the Arduino Leonardo, Micro and Sparkfun Pro Micro family the one that supports that feature.
Hi, according to the specs at store.arduino.cc/arduino-nano a Nano has 22 Digital I/O pins. As with the input HID, you are right, thanks for pointing out :)
@@BasonTech Tend to agree with aveascaner on the number of digital pins. The documentation tab in the link you've provided says "Each of the 14 digital pins .." and , elsewhere , "The nano has 8 analog inputs..". Looks like the 22 digital pins in the tech specs section refers to both analog and digita pins! This is confusing. Also, the diagram of the nano corroborates this - I am able to see the labels of 14 digital pins and 8 analog pins. Am i missing something ?
@@gopalshekar986 I've checked the diagram and table, and I guess you are right. It looks like Arduino.cc counted the analog pins for digital I/O as well. Which is practically correct I guess since you can use the analog pins for digital as well. However it gets a bit confusing when only seeing 14 digital pins.
Theoretically all could in a way. What you need to think of is the minimum Arduino you need. How many I/O, how much processor power. In that wat you can determine the board with the minimal power consumption, and use that one.
Everything depends on your needs. Check that the Arduino you use had the right amount of inputs and outputs, has the correct voltage and form factor for your project
That is new for me. Personally I've never experienced any speed issues. However that is just me. I can imagine some non-official boards could have issues. Do you have a source of this?
I had to look this one up, but found arduino.stackexchange.com/questions/926/what-is-the-maximum-power-consumption-of-the-arduino-nano-3-0 Does this answer your question?
The Arduino Pro Mini spec at arduino.cc/en/Main/ArduinoBoardProMini shows that it has an input voltage range of 3.35-12V (3.3V model) or 5-12V (5V model). If you want to provide your Arduino Pro Mini with 12V you need to supply this on the RAW pin. The Arduino voltage regulator will step this 12V on the RAW pin down to its operating voltage. RAW - Supplies the "raw" voltage to the board and will step it down to its operating voltage. VCC - Is the regulated 3.3V or 5V supply depending on which board you have.
@@BasonTech i still just cant get it To work ! i did everything i saw on the Internet to have data stored in s.d card at a speed of at least 8kbps wich will match the sampling frequecy of the arduino 8000sps .. but i just cant 😭
@@kimhansen6384 Arduino Micro is the smallest board of the family, easy to integrate it in everyday objects to make them interactive. The Micro is based on the ATmega32U4 microcontroller featuring a built-in USB which makes the Micro recognisable as a mouse or keyboard. That's copied from Arduino's website..
I got here trying to understand the difference between does two(nano and pro mini) because I was trying to use the nano as keyboard and after reading because of the microcontroller it is that the micro (and others not listed here) are the ones capable of simulated the keyboard. Although it seems that one with a sort of 2016 library can put to work the nano as well, but I haven't get there. I thought it can suit better to use the capability of the microcontroller installed on the Arduino micro and direct use the keyboard.h library. But for any with further lectures please: how to convert a Arduino nano as external keyboard?
nano can not be used as a HID altho in theory any Arduino can do this they are MCU at the end of the day but the thing is that if you do this to a none Native HID ready device you will have bricked the Arduino to the point of no return, meaning you wont be able to use it after that to upload other scketch as it will be stuck in USB or only recognized as a USB HID device. i just order and got a Pro Micro which is ready for HID just like the Leonardo. Im actually in the middle of making my own BT AirMouse for Gesture control www.arduino.cc/en/Reference/HID
Hi, you don't brick your Arduino. The only thing is that you can't upload via USB anymore. With a standalone programmer you can still upload code to the Arduino. See www.instructables.com/Turn-your-Arduino-Uno-into-an-USB-HID-Mididevice/ This page also describes how to restore the original firmware.
@@BasonTech ahhhh okay thanks for the note, i have a nano that wont upload no more via usb, (bad resistor or cap not sure) any tips or advise on how to upload to it? maybe a red ftdi board or other methods? thanks in advance.
Something wrong with this video! Not correct, are you sure you want put this on RU-vid? An example, arduino pro mini has a0 to a7 analog in! Search on the board! And where's 22 digital pin on the nano?? Something wrong?
Yes, I want to keep the video online since the numbers are correct: Arduino Pro Mini: store.arduino.cc/arduino-pro-mini on the "tech specs tab" it states "Analog Input Pins 6" Arduino Nano: store.arduino.cc/arduino-nano on the "tech specs tab" it states "22 Digital I/O pins"
22digital i/o means we can also use 8analog pins as digital i/o pins whenever needed. So nothing is wrong with the video. I think you are a beginner for electronics
