Arduino Mega 2560 Pinout - Electroschematics

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. While SDA and SCL have internal pullup resistors, SDA1 and SCL1 have not. Adding two pullup resistor on SDA1 and SCL1 lines is required for using Wire1. Arduino Mega Proto

Arduino - InputPullupSerial

Any Arduino pin can be connected to +5V internally by specifying pinMode( pin#, INPUT_PULLUP ). Note that the pullup is only meaningful when the pin is configured as an input. For more information on pull-ups check out the DigitalPins page.

Arduino Playground - PullUpDownResistor

Pull-up resistors are used in electronic logic circuits to ensure that inputs to the arduino settle at expected logic levels if external devices are disconnected or high-impedance. 'Just because you have nothing at all connected to an input pin doesn't mean it is a logical zero.

Leer un pulsador con Arduino - Luis Llamas

The pins on the Arduino can be configured as either inputs or outputs. This document explains the functioning of the pins in those modes. While the title of this document refers to digital pins, it is important to note that vast majority of Arduino (Atmega) analog pins, may be configured, and used, in exactly the same manner as digital pins.

Arduino Interrupts: 5 Steps - instructablescom

Unlike timer interrupts, external interrupts are triggered by external events. For example, when a button is pushed or you receive a pulse from a rotary encoder. However, just like the timer interrupts, you don’t need to keep polling the GPIO pins for a change. The Arduino UNO has 2 external interrupt pins.
