Lego Dacta :: essays research papers

The Input-Output principle means basically that all scuttlebutt devices get the information in and the siding devices show the result.InputsTemp1 (Temperature Sensor) = It measures the temperature.Touch2 (T or F Sensor something pressed) = It works when you touch it.Light5 (Changes in Light) = It blowzys up.Angle6 (Angle changes) = It measures the angle of the devices.OutputsMotorA (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 disparate control impairment used in Lego DactaTalkto = It talks to output devices. For example - talkto motoraOn/ withdraw = It switches on output devices. For example - talkto motora, on, seem 100, off.Alloff = It switches off all output devices. For example - talkto motora, on, setpower 3, see 30, setpower 5, remain 30, setpower 7, abideuntil 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 talkto motora, on, wait 100, off.Waituntil = It makes devices wait until the procedure in the brackets becomes true. For example 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 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 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 to forward1, talkto motora, on, wait 100, off, end.Lego kits can be used in different businesses and organisations like offices, car parks, arcades and banks.
