Accelerometers

How do we sense movement and store and display it? Study this IC and come up with a schematic and software to read and display outputs. See the associated task.

Pin outs

We found that the pins on the Arduino board did not correspond to the pins on the AVR Mega328. Here's a useful mapping of pins. Note the two hardware interrupt pins.

Interrupts

There are two hardware interrupt pins on our Arduino. Interrupt 0 and interrupt 1. These cut off what ever processing is going on and carry out the interrupt service routine that you indicate.
