Challenge 1.1

Display binary numbers (without calculations)

Challenge Level: Beginner

Requirement:

Create a program to display numbers 1, 2, 4, 8 and 16 on the screen, one at a time.

Hints
  • Use the 'Say' block and the 'Number' block to display on the screen what you want. In this case, it will be ‘1’ for the first output, ‘2’ for the second, ‘4’ for the third and so on.

  • Make sure all your blocks are “snapped” together in a line like a jigsaw puzzle.

  • Whenever you click the Run button, your program will start.
