Abstract
Nowadays, almost every house has a doorbell to communicate each present. Many type of doorbell are available in market but rarely find for disabled peoples. For example, if the person is deaf it is difficult for them to know when the visitor is coming. Next problem is when people come at night and cannot see the button of doorbell. Doorbell chime are designed differently from the doorbell that available at the market. This doorbell chime is more inconvenient to all people and disabled people so both can have benefit. For deaf people, Light Emitting Diode (LED) was installed inside the house so that when the visitor press the doorbell button, the LED will light up and they will notice there is a visitor. The visitor also does not have a problem to find the doorbell button because the LED was installed at the doorbell. Light Depending Resistor (LDR) sensor is used to sense the light. So, it will continue flashing automatically when the sun goes below the visible region of the eyes (in evening or dark). For this doorbell chime project, the circuit was simulated using Proteus 7 .10 software.
