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) = Its a moving device i.e. a motor.
LampB (Light go on) = Its 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. For example Ð- talkto “motora, on, wait 100, off.
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.
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.
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.
To/end = It starts/finishes a procedure. For example Ð- to forward1, talkto “motora, on, wait 100, off, end.
