When building prototypes on breadboards I find it useful to have small pre-made components such as 3.5 stereo jack sockets configured to fit breadboards
The 3.5 stereo socket is attached to a small piece of board and the connectors from the socket attached to pins that fit in to a breadboard.
Red is VCC, black is ground, and white is the centre channel or data
I also create mini boards that have more than one component
These have female or male headers and can be connected using standard breadboard wires
