Hi everyone..
i would like to ask one thing:
i have one detecting device which has output as soon as it is activated.
The output is a buzzer and a sound will be given (0.5V).
Now i wanna modify it to from audible to visible by replacing LEDs on it.
i wanna using this output to light up one or more LEDs.
Some people say i can use Opto-isolator or optical coupler to boost up the voltage.
How can i find a suitable Opto-isolator or optical coupler?
and
What specific thing i need to concern?
thank you very much!!
