1. Introduction To Programming with LEGO NXT 0

2. Introduction Why NXT and NXT-G? How it all works What are programs?
Introduction to the NXT-G
Connecting to the NXT Brick
USB
Bluetooth

3. Why NXT and NXT-G?
Programming the NXT robot uses the same ideas any programming language
Sequence
Selection
Iteration
NXT-G is a graphical method of programming
No complicated syntax
Focus on the principles
GREAT FUN!

5. What are programs? Something that: Lego NXT Models a process
Has an entry point
Generally has inputs and outputs
Lego NXT
Line follower
Initialise sensors/servos - START

8. Sensors & Servos

9. Light Sensor This sensor detects ambient (surrounding) light.
It sends out
current light value
logic signal (true/false) based on current light value falling above or below a trigger point

10. Sound Sensor Sound detector detects Audible vibrations It sends out
current sound value
A logic signal (true/false) based on whether the current sound value falls above or below a trigger point.

11. Ultrasonic Sensor
The Ultrasonic sensor detects objects at a maximum range of about 100 inches (250 cm).
It sends out
the current ultrasonic reading
a logic signal (true/false) based on whether the current ultrasonic reading falls above or below a trigger point

12. Touch Sensor The touch sensor detects contact
It sends out its finding as a logic signal (true or false)
If the sensor has been triggered, the block will send out a “true” signal; if it has not been triggered, the block will send a “false” signal
Can detect three conditions
Press
Release
Bump

13. Servos
Both and input and output device
Step Monitor
