UNO är en microcontroller board baserad på ATmega328P
.
Den har 14 digital input/output pins (6 av dom kan användas som PWM outputs), 6 analog inputs, en 16 MHz quartz crystal, en USB kontakt, Strömkontakt, en ICSP header och en reset knapp.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
