Lego Dacta

The "Input-Output" 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 Ð'- 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:

Ð'* Talkto = It talks to output devices. For example - talkto "motora

Ð'* On/off = It switches on output devices. For example - talkto "motora, on, wait 100, off.

Ð'* 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.

Ð'* Wait = It holds devices running for a certain amount of time. For example Ð'- talkto "motora, on, wait 100, off.

Ð'* Waituntil = It makes devices wait until the procedure in the brackets becomes true. For example Ð'- talkto "motora, on, setpower 3, wait 30, setpower 5, wait 30, setpower 7, wait 30, waituntil [touch2], off, end.

Ð'* RD = It reverses motora. For example Ð'- 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.

Ð'* Setpower = It changes the speed of motora. For example Ð'- talkto "motora, on, setpower 3, wait 30, setpower 5, wait 30, setpower 7, wait 30, off.

Ð'* To/end = It starts/finishes a procedure. For example Ð'- to forward1, talkto "motora, on, wait 100, off, end.
