can anyone help me with Opto-isolator and Arduino problems
Now here is the tricky part.
I know that the pos/neg wires are correctly soldered on because you touch them and they make the connection and turn the Remote controlled socket( which is controlled by the remote control) on and everything is lovely. But when the opto-isolator is involved you get the nice blinking LED on the remote control to signal it is sending, but the socket does nothing.
Again i have tried the output circuit on the end of the opto-isolator with a 9v batteries and an LED and they are fine. Working nicely. Another thing to note is that te multimeter showsthat when using the opto-isolator and the remote control the power is the same as if you pressed the button.
I seem to be tearing my hair out here, so anyone who can give me an answer would be on my lifesavers list for life! Before anyone suggests using anything else like a transistor,Relay etc, it must be an opto-isolator as this is a project i want to do centering around opto-isolators.
