Observations
In this activity, When the switch is in the “on” position, the circuit is complete, allowing electricity
to flow to the LED, which glows brightly. When the switch is “off,” the circuit is broken, and the LED
turns off.
Applications
Status Indicators: Used in devices like
computers and routers to indicate power
status, connectivity, and other functions.
Festive Lighting: Used in holiday decorations
and ambient lighting.

Activity Smart Morning Alarm Skills
Overview
In this hands-on activity, we will use the Tinker Orbits Kit to create a Smart Morning Alarm that
activates when light falls on the LDR sensor. This can act as a simple wake-up alarm that sounds
when the sun rises, or it can be used in other light-sensing applications.
Learning Objective
1. How does LDR work?
2. How does a buzzer produce a sound when paired with LDR
Components required
Power Distribution USB Cable LDR Module Buzzer Module Connecting wire Powerbank
