Arduino-Uno
overview
UNO is the perfect microcontroller to get started with electronics and coding. If it's the first time you play with the electronic platform, UNO is the strongest board you can start playing on. ONE is the most used and documented painting of the Arduino family.
Arduino Uno is a microcontroller card based on
ATmega328P (data sheet). There are 14 digital I / O pins (6 of which can be
used as PWM outputs), 6 analog inputs, 16 MHz crystal, USB connection, power
connection, ICSP connector and reset button. Everything you need to support a
microcontroller is included, connecting to a computer with a USB cable or
turning on with an AC-DC adapter or battery to get started. Spend a few dollars
on the tip and start again.
