Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor.

There is a circuit need a 3.5mm stereo audio jack. But the jack I am going to use has 5 pins which is not 3 pins as I think before. Is there someone can explain how it is connected somehow?

Inserting the plug disconnects the pin with the arrow on it. Then you could have speakers connected until the headphone plug is inserted.


If you want to use it as an input, you would connect pins 1,4 and 5 to ground using pins 2 and 3 as your input signals.
