DIY Photosensitive Sound Light Alarm

Photosensitive Sound Light Alarm is a safety or alert system that combines both visual and auditory signals to notify users about specific conditions or events. This system uses a photosensitive component, such as a photodiode or phototransistor, to detect changes in light levels and trigger an alarm when certain thresholds are met. These types of alarms are commonly used in various applications, including security systems, emergency alert systems, and safety devices, to provide both visual and sound cues to the user.
