Arduino Uno is the best board to get started with embedded system programming. If you are a beginner in this field, then this Arduino Uno can be a robust board that you can start playing with it. On this open-source Arduino platform, you may find the full schematic and PCB layout online. Of course, you may also find a huge tutorial on google about home automation and IoT-based projects using Arduino Uno.
Ok. The question is important, but the answer is simple. This is 2021 and Arduino Uno Rev3 that is revision-3 is only marketed by the manufacturer. This is the latest version from Arduino Uno yet.
No way. You may find the genuine version of Arduino Uno here and the price is impressively high. Whereas this is a Chinese version of Arduino Uno.
Although there must be a quality difference between those products, you may be glad to know that there is no hardware issue here. You may get this product at a cheap price rather than a high price genuine version. If you are a beginner, then we will recommend you to play with it first.
All of the Arduino boards are programmed by using the Arduino IDE and this is completely free. You can download the Arduino IDE for Windows, Linux, and Mac operating systems. Sometimes you may be able to find third-party mobile apps to program the Arduino Boards. This is a delight.
So much easy. Yes, Arduino IDE itself may be a user manual or an instructor for you. This IDE comes with all of the basic example programs to start. You may upload the program simply from the IDE.
One more thing, you can also find a huge online tutorial for advanced programming. No limitation is there.
We don’t think so. There is a lot of technical terms there. But if you have an instructor or strong guidance, then it may be processed. If someone is there, with the help of Arduino Uno, it may be great for any science projects.
Arduino Uno may power up with a wide range of dc input voltage, that is 7-12V. We will recommend you to use this SMPS-based AC-to-DC Power Adapter 12V for powering up to your Arduino Uno. But if you want to make it portable, then this 2S Li-Ion Battery with Charger or Mini UPS (5V, 9V, 12V) can be used.
Got it. You may be glad to know that, this product comes with a USB Programming Cable. You don’t have to purchase it separately. But if you want a lengthy cable for more flexibility, then you may purchase it from here.
We are offering the Arduino Uno and all of the accessories at the best price in bd. You can find all of the accessories here. Take a look at the list below and don’t forget to collect it.
All of our Engineers are ready to serve you. If you have any queries, please don’t forget to through a comment in the bellow or simply make a phone call to 09678110110 from 09.00 am to 08.00 pm (7 days a week). You can also join us via Live Chat and Facebook Inbox.

Q: 1)Do you mean that you want to remove the Atmega328P from the board and place ATmega8 or 168 instead? If so, then the answer is No. 2. No. Pinouts are same but these two ICs have different signatures. 3. We are planning to sell Atmega328 with arduino bootloader. Those are supposed to be uploaded soon. 4. Yes. These methods will work. Questioned by A.R, 23-Jun-2014

Q: please help by answering those questions: 1. are all those AVR boards are more or less same? 2.can I remove the MCU with out desoldering? that means only by hand? 3. if the answer of question 2 is yes then;can i program it on that board and and remove it and then then install it on a breadboard to use it? 4.if the pinout config of any other MCU is same as the ATmega328, can i program it by this board? 5.on a site i noticed that it is possible to configure the bootloader form this board to non programed MCU on a bread board. pls tell me that this method is applicable for MCU with of same model or for every AVR MCU? 6. and the final question is: im actually a student from business studies so it is vary hard fro me to understand this items. is it possible to program this board with c or c++ ?(as those are the only languages that i know a little). and actually what kind of programming language is used to config that boards?? Questioned by saadman672, 26-Jun-2014
Very much confusing questions but I am trying to answer one by one: 1) Are you talking about our AVR programmers? If so, then let me tell you, each of the AVR prorammers available here has different technical features but the list of supported micrcontrollers are almost same which can be found at our website or at our suppliers' site. 2)Which MCU are you talking about?The programmer IC? That is the heart of every board! If you take that out your board will not work. However, Progammer ICs are not soldered to the board. So, those are removable. 4) Arduino is not meant for being used as an AVR programmer! 5) You will get the idea from here http://arduino.cc/en/Tutorial/ArduinoToBreadboard 6) I will request you to go through our basic tutorials on arduino if you have not gone through them yet. You will get the basic idea of coding. Answered by A.R, 27-Jun-2014 16:54 PM

Q: Recently I have bought Arduino Uno. But suddenly I have found that Arduino Mega 2560 has a lot more memory than Uno. Will there be any problem with less memory in Uno then Mega for small and medium project? If so, can I exchange my Uno with Mega 2560 and what is the procedure? Please explain. Thank you. Questioned by nazmul_eee, 05-Aug-2014
I don't know what you are planning to do ! But sticking with Arduino Uno is the better choice unless you need more than 14 I/Os (actually 20 I/Os). Because This Arduino Uno board is reusable, once you have programmed the AtMega328P MCU (the removable chip) you can remove it form the Uno board and use the chip on breadboard/PCB with your project. All you need will be a 16Mhz crystal and 2 22pf capacitors to run the chip outside Uno board. And connect your project components with the MCU's pins by following Datasheet ! Again, you can reuse your Uno board by putting a new AtMega328P MCU for another project (bootloader to be burned) ! In this way you save money ! 32kb is fair enough for most project unless you are doing advanced big projects ! From my personal experience I assure you less memory won't be a problem if you program efficiently. Go for Arduino Mega 2560 if your are 1.Connecting 1+ Display units 2.Going to code 300+ lines of codes 3. Need more than 100+ variables (specially unsigned long) 4.Need to control many separate processes This is my personal opinion so do as you please Please check this links if you stick with Arduino Uno http://arduino.cc/en/Tutorial/ArduinoToBreadboard one more think.... with Arduino Mega 2560, if you short circuit I/O your board may be dead forever, with Uno if you make mistake, probably spending 200 taka for AtMega328P MCU you may revive it again ! Answered by suntop, 05-Aug-2014 21:58 PM
You can return your Uno and order mega. You will get your money that you paid for uno back. Please note that we cannot return the vat that we took from you. And let us assure you that UNO works pretty fine in professional projects. Answered by A.R, 06-Aug-2014 11:05 AM
Q: Thanks for the information. Your last point sounds reasonable. I didn't think of mega 2560's compactness. Uno board IC is removable. But mega doesn't provide this facility. Questioned by nazmul_eee, 12-Aug-2014

Q: i have bought it recently, but there were no power supply,where can i get a power supply for arduino uno r3, what is the specification(voltage/current requirement of arduino) of it. thanx Questioned by Hasnat Jamil, 29-Sep-2014
There are few ways you can power it up : First and the most common method is to power it from USB port of your computer For, portable applications use a 9 V battery with LM7805/LD1117/78L05 voltage regulator to get 5 volts For static & continuous application use any 5V adapter with at least 300-500 mA current output. You may use your cellphone charger too ! (check voltage before powering) Answered by suntop, 30-Sep-2014 13:15 PM
If you want to power the uno using its on board power port use DC power jack and supply DC voltage between 7-12 Volts. + inside (hole) - outside (outer shell) Answered by suntop, 30-Sep-2014 13:19 PM

Questioned by robinahmedotul, 26-Dec-2014
Well, Atmega8L is actually intended for up to 8Mhz clock although it worked for me @ 16 Mhz. You may try on breadboard with 8Mhz xtal . Also reburn the boot loader and try again . make sure reset pin is pulled up to Vcc with 10 k resistor . check connections. Most importantly select the right board from your Arduino IDE and update your arduino 'board text ' with proper Chip parameters (see Google ) . upload holae kaj hobe amon kono kotha nai !

You are using old bootloader on your chip (NG / Atmega8) . if you can follow the instructions above about burning Optiboot8 follow that ! There is nothing wrong with the delay you are getting right now ! If was a feature useful in old days , that was used by arduino to wait for new sketch during startup !

The "ATmega328p" on arduino, is pre-installed boot-load system. So why you are trying to boot-load. From your above comment, we are not clear that the problem is on "ATmega32p" or "Arduino Development Board" !!! If the problem occur in the "ATmega328p" chip, then if you buy a boot-loaded ic, it will be work again.

Q: I am disappointed with this product. I ordered a Arduino last sunday , the built in led was not blinking, the rx and tx was not responding. Then i changed it and now most probably because of the bootloader the pin 13 led is always on . I am currently working on a ir reciever project and i am getting junk values on the serial monitor . This is what i did: i connect the middle pin to GND pin 3 to vcc and pin 1 of the ir receiver to pin 11 of the arduino /* * IRremote: IRrecvDemo - demonstrates receiving IR codes with IRrecv * An IR detector/demodulator must be connected to the input RECV_PIN. * Version 0.1 July, 2009 * Copyright 2009 Ken Shirriff * http://arcfn.com */ #include <IRremote.h> int RECV_PIN = 11; int before = 0; int led = 12; //int led2 = 13; IRrecv irrecv(RECV_PIN); decode_results results; void setup() { Serial.begin(9600); pinMode(led,OUTPUT); irrecv.enableIRIn(); // Start the receiver //pinMode(led2,OUTPUT); //digitalWrite(led2,LOW); } void loop() { if (irrecv.decode(&results)) { Serial.println(results.value, HEX); if(results.value==0xB3433BC7) { if(before==0) { digitalWrite(led,HIGH); before = 1; } else { digitalWrite(led,LOW); before=0; } } irrecv.resume(); // Receive the next value } delay(100); } Questioned by Reddhi, 27-Sep-2016

That is quite weird because before giving a replacement we double check the new product. Is the product bad from the beginning or stopped working all in a sudden? Answered by A.R, 29-Sep-2016 10:27 AM
I know that, the arduino was opened when i received it. At first i tried the blink sketch it worked, then i tried a digital read sketch that worked but then i noticed that the pin13 led was still blinking but the sketch worked. But when i tried to serial communicate using a ir receiver i could not get the values , suddenly i used to get a value .The board also has a bright red led instead of the green one.
