ARDUINO PLATFORM & ARDUINO UNO BOARD
Arduino is an open-source electronic prototyping platform based
on flexible, easy- to-use hardware and software, and this is very
good for beginners.
The Arduino UNO is a microcontroller board based on the ATmega328.
It has 14 digital input/output pins (of which 6 can be used as
PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB
port, a power jack, an ICSP header, and a reset button. It contains
everything needed to support the microcontroller.
