I really don't get how they implemented this. ISR (PCINT2_vect) pin change interrupt for D0 to D7 ISR (PCINT1_vect) pin change interrupt for A0 to A5 ISR (PCINT0_vect) pin change interrupt for D8 to D13 I'm not sure which service to use? Apparently my options are: I'm trying to understand the "Simple Pin Change Interrupt on all pins" I'm trying to set it up so that when a limit switch is pressed, I use an interruption (the code will be the same for each interruption for these switches, which I think is good b/c the method I'm trying to use allows for two or more pins to share the same routine. This microcontroller chip is different from the ATMEGA328P in terms of the digital Input / Output pins, Analog pins and other basic features which will be discussed in detail. I can't change these pins given the project rn, but I need to enable interruptions on each of these pins. Arduino MEGA is the open-source microcontroller development board based on the ATMEGA 2560 microcontroller IC. I have pins corresponding to each of my (8) limit switches: pins 40 - 47. From the pin mapping shown in I dont recall why I did that. I am using an arduino mega and limit switches. Awhile ago I did a project in which I connected four digital output ports from one circuit to ports 49 to 52 of Arduino 2560 Mega R3. Introduction The nRF24L01+ 2.4GHz transceiver modules are cheap and very effective but I have come across a few Threads in which people were having trouble with them so I thought it might be useful to gather together in one place a basic step-by-step sequence for getting them to work.
