• Full-Size Breadboards: Full-size breadboards are the
most common type of breadboard and are widely used in

educational settings, laboratories, and by hobbyists and
professionals. They typically have around 800 to 1600

connection points and provide enough space for larger
circuits and experimenting with more complex designs.

Activity LED Glowing Using Tinkercad Skills

Overview

In this activity, you will explore the basics of electronics by creating a simple
circuit to make an LED glow using a breadboard. They will discover how
breadboards work and learn to identify and connect basic electronic components

such as resistors, connecting wires, and LED.

LED (Light Emitting Diode)

• LEDs are small electronic device that emit light

when an electric current passes through them.
• LEDs have two leads (terminal): the longer lead

is the positive (anode) and the shorter lead is
the negative (cathode).

• LED comes in various colours.

Resistor

• A resistor is an electrical component that limits the flow of current
in a circuit.

• It is used to control the amount of current that flows through an

LED to prevent it from burning out.
• Resistors have a resistance value measured in ohms (Ω) that

determines how much current they allow to pass through them.
