+===== Arduino Uno/Duemilanove - Centralna jedinica =====
 Arduino Uno je razvojna platforma zasnovana na [[http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-42735-8-bit-AVR-Microcontroller-ATmega328-328P_Datasheet.pdf|ATmega328p]] mikrokontroleru. Ima 14 ulazno-izlaznih pinova (izvoda) od kojih 6 može biti iskorišteno za pulsno-širinsku modulaciju (engl. //pulse-width modulation, PWM//), 6 analognih ulaza, kvarcni oscilator frekvencije 16MHz, USB konektor za spajanje s računalom, konektor za napajanje, ICSP ( In Circuit Serial Programming ) konektor te tipkalo za reset mikrokontrolera.
