Abstract

The objective of this system is to develop a smart letterbox with reminding and alerting system to reduce the inconvenient for residents. There are two sub-systems in this smart letterbox system namely the Letter Detecting System and Reminding & Alerting System. Both sub-systems are controlled by a microcontroller, PICI 6F877A. The Letter Detecting System consists of IR sensor, IRNG3 which constantly checking the condition inside the letterbox and if there is a letter in the letterbox, the microcontroller will activate the music to alert the residents. This system is designed to detect the letter in the letterbox. Meanwhile, the Reminding & Alerting System is designed to alert the residents when there is a letter. An alerting system will be turned on and LCD will display a proper message for the resident as a reminder. Residents can mute the music manually through a push button. LED attached to the letterbox will be lighted on to alert the resident who are just come back from outside. Constant reminder is use to remind residents in every 5 hour after the music has been manually mute by residents. When residents already collect their letter, constant reminder of music will be turn off.
