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 eight programs. The app comes with demo
programs preloaded in Programs 1-7 and Program 8 is
blank. You will also see that there are other programs for
other versions of the product.
UNDERSTANDING THE ULTRASONIC
DETECTION INTERVALS
1. Enter Program 8 (the 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, which are described on the next page.

REMOTE CONTROL MODE
The ultrasonic functionality will now be available if the
ultrasonic sensor is connected properly. The concentric
circular rings indicate the relative distance to an object in
front of the sensor. The ring lights up when an object is
detected. Closer objects light up the inner rings; objects
that are farther away light up the outer rings. Test it out
by moving an object in front of the sensor.
You can use the two slider controls (C) to directly control
the two motors on your models. Slide the slider up or
down with your finger to make the motor spin clockwise
or counterclockwise.
