Scout Electronics Badge

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 circuits.
• 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.
