Package List: 1 x UNO R3 Development Board Compatible With Arduino UNO R3 1 x USB Cable 1 x Buzzer 1 x Nixie Tube 1 x Temperature Sensor 1 x 74HC595 1 x Infrared Remote Control 1 x Infrared Receiver 1 x Photoresistor 1 x Potentiometer 2 x Tilt sensor 4 x Pushbuttons 1 x RGB 1 x Flame Sensor 1 x Cell Box 1 x 1602 LCD Module Resistors Breadboard & Jumper wires LEDs UNO R3 now uses an ATMega16U2 instead of the ATMega8U2 chip. This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. 3.3VV/5V Supply Voltage and IO Voltage is optional. More 3.3V modules supported, such as Xbee module, Bluetooth module, RF module, GPRS module, GPS module, LCD5110 Backlight and so on, but the original version can only support 5V IO. Controller uses SMD MEGA328P-AU chip. Add A6/A7 port. R3 can directly use the electronic building blocks on I/O port and elicit G, V, S.
