Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
Pupils will develop knowledge of electronic components and a systems approach to designing. They will learn about different components and use these to build and test circuits for different purposes. They will design a system to control a greenhouse environment, considering the different variables.
Lesson Summary
You will learn to explain the function of different buzzers and use them as output components in a control system.
Key Notes
- Buzzers are output devices which convert an electrical signal into a sound.
- There are two types of buzzers, electromechanical and piezoelectric.
- An electromagnetic coil is used in an electromechanical buzzer to move a piece of metal which makes the sound.
- In a piezoelectric buzzer, the smart material flexes and makes the sound.
- Changing the frequency of the movement in the buzzer changes the pitch we hear.
Vocabulary To Learn
- electromechanical: an electrically operated mechanical device
- piezoelectric: a smart material which creates a small amount of electricity when pushed
- electromagnet: a magnet made using a coil, a core and a power supply
Common Mistakes To Avoid
- Buzzers all work in the same way.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
