I'm connecting a phone receiver and transmitter to a circuit board and I'm worried about polarity and potential damage issues.
I'm going to connect the receiver and transmitter shown here which have two wires each from what I see
through this wire
into an 'earphone socket' on an arduino shield.
Is there any polarity issues I have to worry about? Like for example making sure positive ends and negative ends go together or can I just connect whatever wires I want together and experiment with getting a good connection without having to worry about damage?
