The pinout diagrams are simple, but they're easy to read, and especially helpful for beginners. You can print them out full size so you can set your Arduino Uno, ATMega, or ATTiny right on top for ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

If you're on the hunt for the perfect board, then you've probably come across the Uno and Nano. They're two of the most frequently used Arduino variations, but they serve different purposes.

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 ...

The official Arduino team has this week revealed ... “When it comes to hardware compatibility, pinout, voltage and form factor are unchanged from UNO R3, ensuring maximum hardware and electrical ...
