Year 9 - Design and technology

Micro:bits in Tinkercad

Functional prototypes: wearable technology

Unit Summary

Pupils will deepen their understanding of systems and control. They will be introduced to engineered fabrics and the associated manufacturing processes. This knowledge and understanding will be applied through the design and manufacture of a wearable technology product.

Lesson Summary

You will learn to combine inputs, processes and outputs with feedback in a control system.

Key Notes

  • Control systems use inputs such as switches and sensors.
  • Control systems use processes such as microcontrollers.
  • Control systems use outputs such as sound, light or movement.
  • Control systems use feedback.

Vocabulary To Learn

  • microcontroller: a device that can be programmed to control how an electrical product operates
  • program: a sequence of instructions used to control electrical components.
  • feedback: a signal that is sent back in a loop, depending upon a condition

Common Mistakes To Avoid

  • External components must be used with microcontrollers to create control systems.

3 Quick Questions (With Answers)

1. Explain the lesson in two key points.

Control systems use inputs such as switches and sensors. Control systems use processes such as microcontrollers.

2. What does this key word mean in this lesson? 'microcontroller'

a device that can be programmed to control how an electrical product operates.

3. Correct this common mistake.

Mistake: External components must be used with microcontrollers to create control systems. Correction: Microcontrollers have on board inputs and ouputs and connection points for additional external components.
