WRITING PROGRAMS

PROGRAMMING MODE
Press the gear icon (D) to enter the programming mode.
When you press the icon, a list of programs appears. You
can save up to 24 programs. The app comes with demo
programs preloaded in Programs 1-24. You will be using
programs 17-24 in this kit.
UNDERSTANDING THE ULTRASONIC
DETECTION INTERVALS
1. Enter Program 8, which is a blank program. The
programming screen appears.
2. The Go button (E) runs the program. When it is pressed,
the number in the upper left (F) will start indicating the
distance to the object that the sensor is detecting.
3. After you press the Go button, it becomes a Stop button
(G) and the program runs. You can see in this example
that the sensor is reading a distance of "21." This
equates roughly to a distance of 21 centimeters. Press
the Stop button.
4. The sensor distance indicator line (H) has adjustable
ranges. Different program segments can run in each of
these ranges. By default, there are three ranges. The
first range marker (I) is set at 30 and the second marker
(J) at 50. This means there are four program segments
by default:
• The "Opening" program segment (K) runs once at the
beginning when the Go button is pressed.
• When an object is detected between 0 and 30, the blue
0-30 segment (L) runs.
• When an object is detected between 30 and 50, the green
31-50 segment (M) runs.
• When an object is detected between 50 and 100, the
purple >51 segment (N) runs.
You can slide the range markers to change the distance
ranges. You can also increase the number of distance
range segments by pressing the add range marker button
(O). You can delete a segment with the delete button (P).
Range markers must be a minimum of 5 distance units
apart. You cannot add a new range marker if there is
another marker at 90 or higher.
