About Arduino Uno?
Arduino is a popular open-source development board used by engineers, hobbyists, and makers to develop electronic projects and prototypes in an easy way. The Arduino platform consists of many development boards like Arduino UNO, Arduino Nano, Arduino Mega, Arduino Pro Mini etc. all of which are based on the series of AVR microcontrollers. Arduino Uno 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 quartz crystal, 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 an AC-to-DC adapter or battery to get started.

Powering up the Arduino Uno
The Arduino Uno 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 battery. The adapter can be connected by plugging a 2.1mm center-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/Genuino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power sources). 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 generated by the on-board regulator. The maximum current draw is 50 mA.
- GND. Ground pins.
- IOREF. This pin on the Arduino/Genuino 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.
- Applications of Arduino Uno
- Arduino is a hardware prototyping platform that makes it easy for anyone to set up an electronics-based project in a matter of hours if not minutes.
- If you are creating any project related to Digital Electronics, Automation, Robotics, IoT, Datalogger, Etc… the best, effective, easy, cheap, open-source option is Arduino.
- However, do not that Arduino board usually have just a microcontroller and you need to add a lot of extra peripherals to do even simple basic job.
- Arduino Uno is used in Do-it-Yourself projects prototyping.
- In developing projects based on code-based control.
- Development of Automation System, like automatic
- Some Arduino Uno Projects in various fields
- Arduino Sensors Projects
- IoT (internet of things) Projects Using Arduino
- Arduino Medical Project
- Arduino Wireless Projects
- Arduino Bluetooth Projects
- Arduino Home Automation Projects
- Arduino Security Projects
- Arduino Quadcopter Projects
- Arduino RFID (radio frequency identification) Projects
- Arduino Laser Projects
- apart from this, there is an endless project you can work on it without any major problem its easy cheap and there is an infinite possibility to learn and grow.
