The
project is designed to build an incoming phone ring flasher suitable for noisy
environments. A phone line is connected through an opto isolator to drive a
relay whenever telephone ring is detected by the circuit. The lamp flashes
whenever there is an incoming call. This system is highly useful in a situation
where there is lot of noise and it is not possible to listen the phone ring,
such as a workshop, factory etc.
The phone line
is connected to the circuit. This circuit is developed using an opto-isolator
and an electromechanical relay to switch ON/OFF the lamp driven by a transistor.
This concept can be extended in future and implemented in the real time
scenario
