Concept
I created an alarm system that allows users to toggle the alarm on and off using a button. When activated, signified by the green LED, the alarm, represented by a red LED, responds to the surrounding light conditions. Specifically, the red LED turns on when the environment is well-lit and remains off in darkness.
How the Alarm Works
Alarm Setting:
– The user sets the alarm by pressing the blue button.
– The green LED, confirms whether the alarm is actively set (green LED on).
Light Sensing:
– Once the alarm is set, the system relies on a Light-Dependent Resistor (LDR) to detect ambient light levels.
Alarm Activation:
– In a well-lit environment, the red LED, representing the alarm, activates, turns on and off.
Alarm Deactivation:
– In darkness, the red LED remains turned off.
Components Used:
– LEDs: One red and one green
– Light-Dependent Resistor (LDR): Detects changes in ambient light conditions.
– Push-button Switch (Digital Sensor): Enables user interaction to set and unset the alarm.
Reflection
Working on this project I better understand the Arduino programming syntax, and analog input & output. Later when we learn to use sounds and music, I could include a sound for the alarm for better user experience.
