Lego Dacta :: essays research papers

 The “Input-Outputâ€� principle means basically that all input devices get the information in and the output devices show the result.

Inputs

Temp1 (Temperature Sensor) = It measures the temperature.
Touch2 (T or F Sensor – something pressed) = It works when you touch it.
Light5 (Changes in Light) = It lights up.
Angle6 (Angle changes) = It measures the angle of the devices.

Outputs

MotorA (Motor runs) = It’s a moving device i.e. a motor.
LampB (Light go on) = It’s a light up device i.e. a lamp.

These are the different control terms used in Lego Dacta:
•     Talkto = It talks to output devices. For example - talkto “motora
•     On/off = It switches on output devices. For example - talkto “motora, on, wait 100, off.
•     Alloff = It switches off all output devices. For example - talkto “motora, on, setpower 3, wait 30, setpower 5, wait 30, setpower 7, waituntil [touch2], off, wait 30, on, rd, setpower 3, wait 30, setpower 5, wait 30, setpower 7, wait 30, alloff.
•     Wait = It holds devices running for a certain amount of time.
