I am new in to the Arduino programming and this is my first project. I am trying to build a Arduino-DAQ (data-aquisition) device. The device must have a few capabilities, use an intterupt and sleep function, write to and LCD and save data on an SD card.
I have noticed that the digital pin 2 is both used as an interrupt and also as an interrupt for the LCD.
The question is then, can an other ditigal pin be used to as an interrupt trigger, or can the LCD be set up on other pins than digital pin 2 and 3.
If this is possible an example would be very helpfull since i am new to this programming enviroment.
