The Uno is a microcontroller board in view of the ATmega328P. It has 14 advanced info/yield pins (of which 6 can be utilized as PWM yields), 6 simple inputs, a 16 MHz quartz precious stone, a USB association, a force jack, an ICSP header and a reset catch. It contains everything expected to bolster the microcontroller; essentially join it to a PC with a USB link or power it with an AC-to-DC connector or battery to begin.. You can tinker with your UNO without agonizing a lot over accomplishing something incorrectly, most dire outcome imaginable you can trade the chip for a couple of dollars and begin once again once more. 

"Uno" implies one in Italian and was denoted the arrival of Arduino Software (IDE) 1.0. The Uno board and form 1.0 of Arduino Software (IDE) were the reference adaptations of Arduino, now developed to more current discharges. The Uno board is the first in a progression of USB Arduino sheets, and the reference model for the Arduino stage; for a broad rundown of present, past or obsolete sheets see the Arduino file of sheets. 

You can discover here your board guarantee informations.
