Learn how to plot image by turning on a series of LED lights 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 plot image, pause, and clear screen.
What the teacher needs to know / QuickStart Computing Glossary
Program: A stored set of instructions encoded in a language understood by the computer that does some form of computation, processing input and/or stored data to generate output.**
Algorithm: An unambiguous set of rules or a precise step-by-step guide to solve a problem or achieve a particular objective. The guided tutorial follows a algorithm and is a precise step-by-step guide to solve a problem**
Loop: A block of code repeated automatically under the program’s control. ** The blink program introduces Forever. Forever will repeats code in the background forever.
Command: An instruction for the computer to execute, written in a particular programming language.**

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
