Have you seen a blue colored board that is used to develop embedded system projects or making robots? If yes, I think you already using a Arduino UNO, Raspberry pi or Beagle-bone etc. boards to develop something on your own.
Basically Arduino UNO is a open source development board that is used to make different embedded system and robotics projects at the affordable price. It has Atmel’s ATmega-328 micro-controller (8-bit) which is of 28 pins. It is very light board of weight around 25 grams total.
Arduino UNO has 14 digital pins (out of which 6 can be used a PWM outputs), 6 analog pins (used to generate the analog voltage or take an analog voltage input), a crystal of value 16 MHz. Recommended input voltage is 7-12V. Flash memory 32 KB (used to store uploaded program), SRAM of 2 KB (to store variables values), EEPROM of 1 KB (to store permanent data which can be later on).
Many other boards like Arduino Mega, Nano, Pro-mini etc. is also available. The cost of Arduino UNO copy board in India is around 400₹. Be aware of copy board because Arduino community does not make Arduino UNO for India. For outside USA Arduino make Genuino boards. So please don’t give more than 400-450₹ for Arduino UNO in india.
If you want the original one,then you can buy it from Arduino.cc or element18 website which will cost you around 2500₹ including shipping charges.
At the end I have a suggestion for those who want to buy a new Arduino UNO that please check the website of Arduino where they have mentioned how to find the fake or copy boards.
