Why You Should Buy Arduino Uno Original?

Choosing the real Arduino Uno R3 means you're getting the microcontroller board that's been checked a lot, so it's less likely to have problems. It also comes with official help, like a lot of useful guides and forums online, to help you start your projects and fix any issues you might have. 

Arduino Uno Pinout

The Arduino Uno R3 board can be powered via a USB connection or with an external power supply. The power source is selected automatically.

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or a battery. The adapter can be connected by plugging a 2.1mm centre-positive plug into the board's power jack. Leads from a battery can be inserted in the GND and Vin pin headers of the POWER connector.

The board can operate on an external supply from 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

The power pins are as follows:

  • Vin. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
  • 5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
  • 3V3. A 3.3-volt supply is generated by the onboard regulator. The maximum current draw is 50 mA.
  • GND. Ground pins.
  • IOREF. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs to work with the 5V or 3.3V.

1. What is an Arduino Uno used for? 

  • Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, and Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output 

2. What is Arduino Uno in IoT? 

  • Arduino is an open-source hardware platform that is readily available for hobbyists & enthusiasts across the globe to build projects. It includes an ATMEGA microcontroller that processes data and ensures the IoT system's proper operation. 

3. Why Arduino Uno is best? 

  • One of the best Arduino boards for beginners is the Arduino Uno. It's very user-friendly while also providing excellent connectivity. For projects that require an external power jack, there's an onboard LED indicator, USB B controller, and excellent power handling on the input/output (I/O) side. 

4. Why is Arduino so popular? 

  • So the Arduino hardware is easy, the Arduino IDE is simple, and the code itself is much easier to comprehend (than trying to program an off-the-shelf microcontroller). That's a big part of why Arduino is so popular.
