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 ...

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.

But looking at the below table, it’s clear that we can’t try both OC0B ... sketch prepared for Arduino and ATtiny85: int PWM_pin = 9; // LED pin for Arduino Uno (D9) //int PWM_pin = 0; // LED pin for ...

and additional SDA and SCL pins. Since the discontinuation of the original and Rev2 boards, the Rev3 has become the face of the Uno family and the Arduino brand in general. In fact, it's ...

the Arduino 101 is pin compatible with Arduino Uno R3 shields, it's 5v tolerant even though it's designed for low power 3.3v operation, and it's fully compatible with the Arduino IDE. The purpose ...

Most of us are familiar with the Arduino ... pin layout (Arduino shields likely won’t fit) and more I/Os than the ATmegas have. Sure, it’s not as practical as an actual Arduino Uno, but ...

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 ...
