Description of Arduino Uno R3

Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your Uno without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.

Pinouts


Power

The Arduino Uno board can be powered through the USB connection or an external power supply, with automatic power source selection.

External (non-USB) power can be provided using an AC-to-DC adapter or a battery. The adapter connects via a 2.1mm center-positive plug to the power jack, while a battery can be connected through the GND and Vin pins of the POWER header.

The board operates on an external input voltage range of 6 to 20 volts. For stable and safe operation, a supply of 7 to 12 volts is recommended. Voltages below 7V may cause instability, and voltages above 12V may overheat the voltage regulator and damage the board.

Power Pins

  • Vin – Input voltage when using an external power source.
  • 5V – Regulated 5V output from the on-board regulator. Supplying power directly through this pin is not recommended.
  • 3V3 – Regulated 3.3V output with a maximum current of 50 mA.
  • GND – Ground pins.
  • IOREF – Provides the operating voltage reference of the microcontroller for shield compatibility.

Application

  • IoT Projects: Smart home automation, wireless sensors
  • Robotics: Line follower, obstacle-avoiding robot
  • Sensor Systems: Temperature, motion, and gas detectors
  • Educational Use: Ideal for STEM learning and engineering labs
  • Home Automation: Automatic lights, fan, and remote-controlled appliances

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.

Any other accessories for Arduino Uno?

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.
