SELECT THE HABIT YOU WANT TO LEARN MORE ABOUT. Is there one that makes
you the most happy, passionate, or upset? It’s always good to work on something
that means a lot to you.
LOOK THROUGH YOUR BITS
TM
AND MATERIALS AND THINK ABOUT HOW EACH
ONE COULD MEASURE OR TRACK THAT HABIT. Could the button help you know
when something is moved? Could the light sensor detect when something is
opened?
SKETCH OUT IDEAS, PICK YOUR FAVORITE, AND CREATE A PROTOTYPE OF A
DATA-COLLECTION MACHINE. Don’t worry about getting everything right on
the rst try. The important thing is to just get started and experiment. Building a
physical model of your idea will help you gure out the best way to track habits.

CREATE A LIST OF THINGS YOU OR YOUR
CLASSMATES DO THAT YOU WANT TO KNOW
MORE ABOUT. Maybe it’s a habit you’d like to
improve on (how can I make fewer trips to my
locker?), something you’re curious about (how
many high ves can I get in a day?), or an issue
you’d like to help other people understand (why
don’t your classmates recycle?). Try to list as
many dierent habits as possible.
PRO TIP: PAIRING AN INPUT BIT

WITH THE NUMBER (IN COUNT MODE)
CAN BE A REALLY HELPFUL COUNTER
IN THIS PROJECT.
