SCRATCH CODING KIT

Explanations

Pelicana robot

Look at the flowchart. When the program starts, the DC motor has to operate and the digital output should be

turned on when the button sensor is pressed. The program should keep checking if the switch was pressed or not.

Do you remember what we learned in using the button sensor?

First, ‘if..or else’ block would be used as the start of the program, and whether the button sensor is pressed or not

will be the condition. If the condition is satisfied (if the button is pressed), dc motor will rotate clockwise, and the

sound sensor will produce the sound by turning on the digital output.

If the condition is not satisfied (if the button is not pressed), the DC motor stops, and digital output turns off,

making no sound. You will be able to do it since it’s a simple script!
