SCRATCH CODING KIT

Operator

Using the operator

Now, we are going to use the volume sensor with the operator and analog values to activate the motor. Look at

the flowchart below and say the program is going to keep repeating.

The program will keep checking if the value of the volume sensor is bigger/smaller than the original value.

Remember that the value of the analog sensor goes up when the sensor is covered and it goes down

when the sensor is uncovered.

You have to set a value that will stop the motor when you rotate the servocell on the

windmill’s volume sensor. This is called ‘threshold’.
