Each of the 14 digital pins on the Arduino Uno can be used as an input or output ... These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip. PWM: 3, 5, 6, 9, 10, ...

A few other distinctions you'll notice between the two boards' pinouts are that ... Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies ...

The Arduino Uno is the old standby of the Arduino world ... cool piece of kit combining a Linux system with the Arduino pinout. Care to take a guess at what the next Arduino board will be called?

now dubbed the Arduino Uno. It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac ...

Since the interrupt signal comes from outside the Arduino it is called as external interrupt. Arduino Uno R3 has two external interrupts: int.0 (pin 2) and int.1 (pin 3). While connecting a RT to ...
