Electronic Components

These pages are intended to help you to identify components, find out their values and learn about their function in circuits.

• Capacitors
• Connectors and Cables
• Diodes including zener diodes
• Integrated Circuits (Chips)
  • 4000 series logic ICs (pin connections etc)
  • 74 series logic ICs (pin connections etc)
• Lamps
• LEDs (Light Emitting Diodes)
• Relays
• Resistors
  • Resistor Colour Code Calculator
• Switches
• Transistors
  • Heat sinks for transistors
• Variable Resistors
• Other components including LDRs and thermistors

If you are new to electronics you may wish to see the page with advice on buying a starter kit of components.

To find out what precautions, if any, need to be taken when soldering components please see the page on soldering. This site also has a table of circuit symbols which includes brief information about the function of each component. You can use the simple tester project to check many of the components.
