Model : ARD-00028
Supplier : Made in China
TechshopBD, Bangladesh
We are offering you the best Arduino Uno Price in BD
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.
Which variant of Arduino is best for you compared to the Price in BD?
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.
Is this Arduino Uno original or clone?
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.
What’s about the Arduino Uno Programming?
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.
How can I learn?
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.
Is this Arduino Uno safe for children?
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.
How to power up the Arduino Uno?
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.
What’s about the Programming Cable for the Arduino Uno?
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.

I am feeling unhappy about it!
So far, working great !
Tested some analog digital I/O's with LED.
Planning on making a LED Thermometer !
1.Will this board (Arduino Uno) support ATmegaA8 and ATmega168 micro controllers ?
2. Is ATmega328 and ATmega328P are same chip ?
3. If I buy ATmega328P micro controller form Techshop, will you burn the bootloader in it before shipping (for Arduino Uno R3 board) ?
4. Please check this link :
http://arduino.cc/en/Tutorial/ArduinoToBreadboard
Is this the method to burn bootloader in ATmega328P ?
Please reply.... I will be waiting for your answers !
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.
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??
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.
Please follow this link to burn boot loader:
http://nirzaree.wordpress.com/2012/03/07/make-a-standalone-atmega8-circuit/
Limitation :
Start up will be 8 sec slower
Limited Memory (7.5 KB)
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 !
You will get all details here.
It's called GoBetweeno
here is the link
http://playground.arduino.cc/Interfacing/GoBetwino
2. Why does the original cost TOO much?
3. Is Chinese one compatible with win 8.1 64 bit?
2)Quality never costs chip. You can verify the price from arduino.cc and the page link of our supplier,sparkfun.
3. As far as we know these are compatible with windows 8. But special instructions must be followed ashttps://www.youtube.com/watch?v=CdE72XUYC7k#start=0:00;end=2:25;cycles=-1;autoreplay=false;showoptions=false

thanx
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)
+ inside (hole)
- outside (outer shell)

and at the end paste :
##############################################################
# Custom board "Arduino Optiboot8"
# Arduino uno r3 ATMEGA8A-PU
opti8.name = Arduino Optiboot8
opti8.upload.protocol = Arduino
opti8.upload.maximum_size = 7680
opti8.upload.speed = 115200
opti8.bootloader.low_fuses = 0xBF
opti8.bootloader.high_fuses = 0xcc
opti8.bootloader.path = optiboot
opti8.bootloader.file = optiboot_atmega8.hex
opti8.bootloader.unlock_bits = 0x3F

opti8.build.mcu = atmega8
opti8.build.f_cpu = 16000000L
opti8.build.core = arduino
opti8.build.variant = standard
Now burn bootloader using as usual method selecting "Arduino Optiboot8" as board !
Note : When you are first uploading the ArduinoISP sketch, select board "Arduino UNO" or whatever is your actual board is !
Next, when you are about to burn the bootloader on virgin Atmega 8A using the main board as ISP (In System Programmer) change the board name to "Arduino Optiboot8" before clicking "Burn Bootloader"
Use fresh/new Breadboard or Zif socket (28 pin) for such purposes !

Original is always better. This is good too.
a ATmega328P but it failed. After i swapped the ICs every thing stopped working.
So if i buy a bootloaded IC ATmega328 will my arduino work again or i need to buy another one??
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. To buy a boot-loaded ic, please click the link bellow:

Thanks for with us.
আমি আপনাদের কাছ থেকে একটি ' Arduino UNO R3 কিনেছি।সেটায় একটা সমস্যা দেখা দিয়েছে। সমস্যাটি হল:
অরডুইনোটি যথারীতি আপগ্রেড দেওয়ার পর প্রায় সিব টিউটোরিয়াল এর সাজেশন অনুযায়ী আমি 'Blink' প্রোগ্রামটি আপলোড দেই এবং সেটি ঠিকমতোই কাজ করছে।কিন্তু সমস্যা হল,এখন আর কোনো নতুন প্রোগ্রাম আপলোড নিচ্ছে না।যেখানে আপলোড সেকেন্ডের কাজ,সেখানে প্রায় ৫ মিনিট ধরে আপলডিং দেখিয়ে এরপরে শো করে,"Uploading eror" অথবা "problem uploading the board "
অনেকবার অনেকভাবে চেষ্টা করেছি। অরডুইনো সফটওয়্যারটি আনইন্সটল করে আবার ইন্সটল করেছি,বারবার আপলোড করার চেষ্টা করেই যাচ্ছি,একই অবস্থা।
কি করা উচিত আমার???
প্লিজ একটু সাহায্য করুন!!!

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.
