Year 9 - Design and technology

Code and simulate 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 develop a light sequence control system, and test and iterate it.

Key Notes

  • Micro:bits are small computers which are are programmed using codes and blocks.
  • Light sequences and loops can be used to develop control systems further.
  • Control systems can be simulated within Tinkercad and also in the physical world.

Vocabulary To Learn

  • program: sequence of instructions that can be used to control electrical components
  • sensor: a device that can detect and monitor changes
  • simulate: to imitate a product or process to test it

Common Mistakes To Avoid

  • A light dependant resistor (LDR) only senses light levels.

3 Quick Questions (With Answers)

1. Explain the lesson in two key points.

Micro:bits are small computers which are are programmed using codes and blocks. Light sequences and loops can be used to develop control systems further.

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

sequence of instructions that can be used to control electrical components.

3. Correct this common mistake.

Mistake: A light dependant resistor (LDR) only senses light levels. Correction: An LDR's resistance changes depending on the amount of light it is exposed to. As the light level increases, the resistance decreases. This change in resistance can create a voltage change, which can be used as a signal to control an output.
