Project: Morning Alarm Clock
Morning Alarm Clock
Let’s try one more project and see how we can use a Light sensor in a morning alarm clock.
Component Required :
The components required for this project are:
Power-1
LDR -1
Buzzer -1
Gray Plate -1
CT2-10
Power Bank -1
USB to DC jack -1
Circuit Connection :
Now let’s start with the circuit part.
Take a power block.
Add a Light sensor to it.
Now join a buzzer block.
Power the circuit with Power bank and USB to DC Jack.
Mount the whole circuit on Gray plate and turn the power ON.
Now Place the circuit near your bedroom window at night. Don’t forget to turn the Power switch ON.
As the Sun rises the sunlight’s falls on the Light Sensor. Due to which the resistance decreases and current starts flowing through the circuit increases. Hence the Buzzer starts buzzing.
