Block program

Commentary

In lines 3 to 6, we prepare to output the message to the browser screen.
The label variable is a variable that displays the specified letters and numbers on the screen.

Lines 4 and 6 set an empty character in the label variable. There is no output on the screen.
(If you don’t set an empty character, the character label will be printed on the screen.)

The distance sensor will continue to measure the distance from the lid in the “Run all the way” block after line 6.

In the ” if” block, if the sensor distance is greater than 20cm (when the lid is opened), the label variable is rewritten.

A message saying “Happy Birthday to You” is output on the browser screen, and a birthday song (Happy Birthday) is played.

As soon as the song ends, the following message will be output. Try to make the content of your message unique to that special someone.
