The Uno also has a limited number of pins, making it difficult to work with when the project requires plenty of input and output components. However, these two areas are where the Arduino Mega shines.

Figure 5: Serial window. Both Arduino 101 and Arduino UNO have 20 I/O pins. Arduino 101 has more pins that can accept interrupts than Arduino UNO. Arduino UNO can trigger an interrupt on digital ...

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 ...

Conversely, the Uno's pins are female. Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you ...

The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...
