Observations

In the LED Glowing using Tinkercad activity, you will observe how the LED lights
up when the circuit is completed with proper voltage and current control. They
will see how the resistor prevents the LED from getting too much current and

how the voltage regulator ensures a stable 5V supply. This activity provides
hands-on experience in building a basic circuit, teaching them about the role
of resistors, LEDs, and voltage regulation in electronics.

Application

Decorative Lighting: LED glow circuits are widely
used in decorative lighting applications, such
as holiday decorations, architectural lighting,

and mood lighting in homes, restaurants, and
entertainment venues.

Activity Mood Light Circuit Using Tinkercad Skills

Overview

In this activity, you will create a mood light using an RGB LED. By connecting
the RGB LED to a breadboard, they will learn how to control the LED to display

different colours, creating ambient lighting effects. This activity introduces
basic concepts of colour mixing and circuitry for mood lighting.

RGB LED

• An RGB LED is like having three tiny LEDs in one package, each

emitting red, green, or blue light.
• By adjusting the brightness of each colour, we can mix them

together to create different colours.
• This allows us to create colourful displays, mood lighting, and

dynamic effects in electronic projects.
