Computing Y4 S4 TA
I can use Lego WeDo to create and control a simulated physical system (Aeroplane).
To be successful you will need to follow instructions and build a simulated aeroplane which has a built in tilt sensor. You will also need to create a sequence to control the motor, display messages and change the background. You will use techniques and language already learnt in previous sessions including: repeats, variables, inputs, outputs, waits and sensing.
Steps to Success
I understand how a display sequence with a delay works
Explain what this sequence does. Tick the right one.
Displays ‘1’ and then ‘Hello’ on the screen ⃞
Clears the screen, background 1, then displays ‘Hello’ ⃞
I understand how to use WeDo motor control
Tick the block that controls how long the motor stays on for.
I understand the use of a tilt sensor
When will the motor spin? Tick the right one.
As soon as the green arrow is selected. ⃞
Only when the model is tilted ⃞
I can debug
I want the motor to start once I have tilted the plane. What is wrong with this sequence? Tick the problem.
The wrong sensor is in the sequence ⃞
The sequence is not waiting for a sensor before starting the motor ⃞
