Note 10A • PARADAY Program
This program reads either the CBL with a motion sensor or the CBR.
Jump Option
Place the motion sensor on the floor pointing at a wall or object 1 meter away.
Have the jumper stand halfway between. The jumper should jump after the
sensor begins to “tick.”
Roll Option
Place the motion sensor on the high end of an inclined table. An empty 2-lb
coffee can works well for this experiment. Starting at the low end of the table,
roll the can gently up the table when the sensor begins to “tick.”
Get Data
When you are happy with the data you have gathered, you can link another
calculator to the CBL and choose
3:GET DATA
to retrieve the data into a second
or third calculator. This will save you the difficulty of linking and sending lists
among different models of calculators in the same group.
