Arduino Uno R3 – Frequently Asked Questions


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. 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 the Arduino Uno Rev3, which is revision 3, is only marketed by the manufacturer. This is the latest version of Arduino Uno.

Is this Arduino Uno original or a clone?

No way. You may find the genuine version of Arduino Uno here, and the price is impressively high. 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-priced genuine version. If you're a beginner, we recommend trying it out 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 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 recommend that you use this SMPS-based AC-to-DC Power Adapter 12V for powering up 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.
