How to earn your badge
- Identify a number of common electronic components that are shown to
you. Explain, in simple terms, the functions they perform in electronic
- Describe the systems used for marking components with their values. Demonstrate by identifying the values of resistors and capacitors by their markings. Explain the importance of the rating of a component.
- Show that you know the symbols used to represent common components in circuit diagrams. Show how to identify the polarity of a diode and a specific pin number on an integrated circuit.
- Show that you’re aware of the safe working practices to be followed when handling electronic components, circuit boards and when soldering.
- Use a multimeter to measure voltage, current and resistance in a simple circuit. Explain the relationship between these values.
- Talk about the main differences in the operation of digital and analogue circuits.
- Construct three simple circuits. One of these should be based mainly on digital electronics. They can be from a book or magazine, or you can design the circuits yourself. If possible, at least one of the circuits should be soldered using either stripboard or a custom-made printed circuit board.
- Explain the principles behind the operation of each circuit and the typical values of voltage and current found in each.
- Explain the possible uses of the three circuits you built.
- Talk about the uses and benefits of electronics in everyday life. Explain how electronics can be used to improve lives.
