9 My Blocks
Custom Palette allows you to
1. Create and name your own block
(including the icon) that you can use
over and over in different programs
2. Simplify your program
Today, you will
Continue
to work on the first two courses
Use the NXT editor to complete the following
(Tutorials 8 and 9)
Use the Loop Block to repeat actions
Create My Block for customized code
Time
permitting: Working with Light Sensor
Build the Light Sensor
Work on Tutorial 16 Detect a Line
Work on Tutorial 17 Follow a Line
Last
15 minutes of class: Instructions for Dance
Contest will be revealed
Requirements for Dance Contest
Time

Inside of a loop
Use at least 1 image

Use
10 Blocks or more
Musical Robot: Sing a Song
Use
a variety of Sound Blocks to play a
song.
Each Sound Block would have a different
tone with different duration
Consider using Loops and My Blocks to
shorten your program
Before working with Light Sensor:
Calibrate Light Sensor
To use the method built into the NXT software,
connect your NXT to your PC (with the NXT cable
or Bluetooth), then select the Tools -> Calibrate
Sensors menu item, choose Light Sensor, and
choose the correct sensor port (port 3 is used by
these line following programs) and press the
Calibrate button. At this point the software will
download a program called "Calibrate" to the
NXT and run it. Place your robot over the surface
to be used and use the screen prompts to sample
the two values
After calibration, "Black" should report very close
to 0 and "White" very close to 100
Light Sensor Challenge with
Switch
On
a white surface, detect a color
change.
When you reach green, have the brick say
something special (like “Hello”).
When you reach black, have the brick say
something different (like “Good Bye”). Brick
should also stop.
