Hello all and thank you for having me.
Would like a little bit of help please.
I'm just getting to grass with electronics but here's the issue I have.
I have a cordless phone where I have pulled out the red and the black wire which would normally go to the speaker.
I have connected them to the 4N35 and on the other side I have connected an LED.
The ring there is not a consistent pattern. So the LED flickers on and off.
I need to find a way to get it to turn on a relay and to keep the relay on during the duration of the ring. I thought maybe I would have to use a capacitor but I'm not quite sure.
I have been looking online and am actually happy that I got the LED to work. But it does flicker on and off when it rings.
Thanks
