For this assessment you will need to create your own electronics output.

You will need to design a brief that the teacher approves on and meets the requirements.

It needs to be an outcome that meets the requirement of the assessment and uses complex* techniques.

*examples of complex techniques:
  • implementing communication protocols e.g. i2C, serial communications
  • wireless transfer of information
  • feedback control
  • implementing software flags and interrupts
  • CAD design, 3D printing, CNC, PCB making
  • filtering, noise and EMI suppression. ​

The main focus of this assessment is on the testing, evaluation and justification of choosing the components you wish to use.

You will want to refine and review your components so that your outcome is more reliable.
​

Grading

Achieved:
  • Uses appropriate resources and techniques to develop a functional electronics outcome
  • Constructing, testing, and analysing functional circuits to ensure that the electronics outcome performs to specifications
  • Testing, modifying, debugging the outcome
  • Explaining the behaviour and function of the electronics outcome
  • Explaining relevant communication protocols
  • Addresses relevant implications.
Merit
  • Using information from testing and analysis to ensure the circuit(s) functions reliably.
Excellence
  • Justifying the choice of communication protocols 
  • Undertaking iterative improvement throughout the design, development and testing process
  • Justifying the choice of components and subsystems

Pathway

1.) Select a brief and work with the teacher to ensure that it is suitable for the assessment. Does it met the criteria for an advanced electronics outcome.
2.) Explain the relevant implications to the outcome
3.) Create a design of your outcome
4.) Seek feedback and update your design
5.) Explain the behavior and function of the outcome.
(This will include an explanation of what the outcome does and how the components work together to make this happen. )
6.) Choose the components\systems for your outcome
7.) Explain and justify the choices you have made when choosing the outcomes
8.) Iterate your outcome and refine it until it is reliable. Using evidence show how you have iterated and how it is reliable.
​9.) Show evidence that you have addressed relevant implications

Glossary/Terms

Component:
A component is a physical electronics component, such as an actuator or sensor.
System:
A system refers to the programming behind a particular subsystem.
Explain:
An explanation can answer these questions: Who, What, Where, Why and How.
Justify:
An argument as to why your outcome meets certain criteria, Weigh up evidence and make an argument.
Reliability:
Does your outcome function easily without any issue, is it easy for the end user? does it sometimes present errors.?
