You can create your calculation in the Calculator text
box inside the Smart Fan Accessory window, or click the
Calculator icon in the Tools palette to open the Calcula
-
tor window.(See the software Help system for more
information.)
•
The top part of the Calculator window shows a list
of Calculations. (In this example, the list shows
“Thrust1=”.) Below the list is a row of buttons for
selecting degrees (DEG), radians (RAD) or “Timer
Mode”, and “Edit Calculation Properties”.
•
The lower part of the window starts with a row of
special editing tools.
•
Below the tools are the types of calculators, the
calculator functions, basic arithmetic functions and
the text area that shows information about each of
the calculator functions.
Example Calculation with Start Condition
This example assumes that the Smart Fan Accessory is
connected to a Smart Cart, and the Smart Cart is wire
-
lessly connected to a computing device.
In the Calculator text area, create an equation as fol
-
lows. First, enter “-100”. Second, click the “Insert Data”
editing tool and select “Position, Blue (m)” from the
menu. Third, click the “Accept” button.
•
Thrust1=-100[Position, Blue (m)]
Under Advanced Options, set the Start Condition to
“Measurement Based”, the Data Source to “Position,
Blue (m)”, the Condition to “Rises Above”, and the Value
to “0”. Set the Stop Condition to “None”.
Check the box for “Auto”.
Place the Smart Cart in the middle of a level track or on
a horizontal surface. In the software, select “Record”. Move the Smart Cart in a straight line a short dis
-
tance (such as 30 to 50 cm) away from its starting position, and then let go of the cart.
As soon as the Smart Cart is moved away from its starting position, the fan will come on and provide
thrust to return the cart. However, the cart will pass the starting position and the fan will reverse direction
to push the cart back toward the starting position again.
Note: Due to the aerodynamics of the Smart Fan Accessory, the thrust in one direction will be more
effective than the thrust in the opposite direction.
