In this video, we understand the detailed features of the Arduino UNO board

The major components of the Arduino UNO board stand as follows:

  1.  Power Supply – USB connector
  2.  Power port – Input from the Adaptor
  3.  Microcontroller – ATmega328
  4. Analog Input Pins – A0-A6
  5.  Digital Pins – D0-D14
  6. Reset Switch
  7.  Crystal oscillator – 16MHz
  8.  ICSP Connector for Programming
  9.  Tx and Rx LEDs So we understand in dept of every component, It’s a requirement.
