Electronics Components

Throughout this unit, we'll unravel the mysteries behind switches, which control the flow of electricity; resistors, which limit and manage electrical currents; and LEDs, which bring light to our electronic creations.

Lesson Title: Knowing Basic Electronics Components

Grade Level: High school (10th-12th grade)

Subject: Applied Design, Skills and Technology (ADST) Electronics, also applicable for Science and Physics

Duration: ~60 minutes

Required Equipment: Power Supply, Multimeter, Laptop with Wi-Fi access

Required Components: Breadboard, Resistors of varying values, LEDs, Sliding Switch, Push Button


  • Identify and describe common electronic components such as resistors, LEDs, switch, wires

  • Understand the function and properties of each component

  • Demonstrate the use of these components in simple circuits

  • Understand how to use Breadboards and be able to light up a LED

  • Know how to use multimeter (Circuit Testing tool) and power supply


Introduction (10 mins)

  • Introduce the topic of electronics and provide an overview of the lesson

  • Review the basics of electricity and what is DC circuits

  • Introduce the different electronic components that will be used in the lesson

  • Teach all the equipment (multimeter, power supply, Breadboard) will be used in the lesson

Simulation Activity (15 mins)

  • Introduce students to a chosen simulation software/platform.

  • Demonstrate how to set up a basic circuit within the simulation, emphasizing the virtual components' similarities to their physical counterparts.

  • Let students replicate the process, creating and testing their virtual circuits, starting with simple tasks like lighting up an LED.

Hands-on Activity: Building Simple Circuits (20 mins)

  • Demonstrate how to set up a basic circuit on a breadboard, starting with lighting up an LED on Breadboard.

  • Students follow along, setting up their circuits.

  • Guide students in experimenting with switches to control the LED.

Using Measurement Tools (10 mins)

  • Introduce the multimeter, discussing its functions and parts.

  • Demonstrate how to measure voltage, resistance, and current.

  • Let students practice measurements on their circuits.

  • Briefly touch upon the use of the power supply, ensuring students understand its importance and safe usage.

Conclusion and Recap (5 mins)

  • Review the main points covered in the lesson.

  • Emphasize the significance of each component in real-world applications.

  • Encourage students to share their observations and findings from the hands-on activities.


Formative assessment: Students will participate in class discussions and activities, and successfully build and test circuits using both the Tinker CAD simulation tool and hands-on experimentation.

Summative assessment: Students will complete a written assessment that includes identification of components and their properties, reading and interpreting circuit diagrams, and the ability to build and test circuits using both simulation and hands-on experimentation.
