Arduino UNO Board:
We discussed What is Arduino? and its introduction in our previous article. Now we move towards the most popular board from Arduino family i.e. Arduino UNO Board.
The Arduino UNO is the best and Number one choice to get started with electronics and coding.
If this is your first experience of using the Arduino platform, the Arduino UNO Board is the most robust board that you can start experimenting with it.
The UNO is the most used, popular and well-documented board of the whole Arduino family.
Arduino UNO is an 8-bit microcontroller board with on the ATmega328P 8bit-AVR controller.

Features:
- It has 14 digital IO pins (of which 6 pins can be used as pulse width modulation (PWM) outputs) (IO – input/output)
- It has 6 analog inputs
- One quartz crystal with 16 MHz
- Single USB Port
- One power jack
- An ICSP header
- A reset button.
Power:
- You can power the Arduino Uno with the USB connection or with an external power supply.
- It can select available power sources automatically and the recommended power range is 7 to 12 volts.
Complete Board:
- This Board contains everything needed to support the microcontroller and you have to simply connect it to a computer with a USB cable or provide power it with an AC-to-DC adapter or battery to get started.
