Learn how to show LEDs by showing an image on the LED screen. We will be learning how to create a blinking app using a forever loop as well as simple commands, such as show LEDs, pause, and clear screen.

Documentation

Objectives

  • learn how to repeat code in the background forever
  • learn how to show LEDs on the LED screen
  • learn how to pause your code for the specified number of milliseconds
  • learn how to turn off all the LED lights on the LED screen

Progression Pathways / Computational Thinking Framework

Algorithms

  • Understands that iteration is the repetition of a process such as a loop. (AL)
  • Represents solutions using a structured notation. (AL) (AB)

Programming & Development

  • Creates programs that implement algorithms to achieve given goals. (AL)
  • Declares and assigns variables.(AB)

Data & Data Representation

  • Understands the difference between data and information. (AB)
  • Defines data types: real numbers and Boolean. (AB)

Information Technology

  • Collects, organises and presents data and information in digital content. (AB)
  • Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution. (EV)

Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
