Embedded Project on Incoming Phone Ring Light Flasher


The project is designed to construct an approaching telephone ring flasher appropriate for noisy environment conditions. A phone line is connected through an opto isolator to drive a relay at whatever telephone ring is identified by the circuit.

The lamp flashes at whenever there is an incomming call. This framework is highly helpful in a situation where there is lot of noise and it isn’t  possible to listen the telephone ring, for example, a workshop, manufacturing plant and so forth.

The phone line is associated with the circuit. This circuit is created utilizing an opto-isolator and an electromechanical relay to switch ON/OFF the lamp driven by a transistor. This idea can be extended in future and executed in the real time scenario.
