Learn how to control a blinking LED. We will be learning how to create a blinking app using the for loop as well as simple commands, such as plot and pause.
What the teacher needs to know
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 a While Loop. While Loop is a while loop that will repeat code forever while - true.
Command: An instruction for the computer to execute, written in a particular programming language.**

- create a for loop that will loop through each x-value, y-value from 0 to 4.
- learn how to pause the light on and off
- learn how to repeat turning on and off the light

Progression Pathways / Computational Thinking Framework
Algorithms
- Uses logical reasoning to predict outputs, showing an awareness of inputs. (AL)
- 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)
- Uses a variable and relational operators within a loop to govern termination. (AL) (GE)
- Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (AL)
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
