Can I use my 3.5 mm audio port similar to the micro usb port for serial communication? I wan to create an app which connects via the audio port and can be used to control an LED? Also I have build a similar app using bluetooth module. How can I use it to communicate via micro USB?

  • The question is so confusing that I don't know what you really want to achieve. I understood the part about audio port and LED, but how is it connected with micro usb?? – XorOrNor Dec 30 '13 at 15:53
  • I want to achieve it via either of the two: audio port or the micro usb port whichever is easier. Basically I want to control an led through either of the ports. I have done it via bluetooth. Any solutions? – user3086548 Dec 30 '13 at 15:59

Be careful with voltage levels and with impedances... you risk to fry your audio chip!!

Now, at your risk: see if these link will suggest you some ideas:

  • Do you know any link to a project or can you suggest how to use either the audio port or the micro USB port for serial communication similar to bluetooth which is quite simpler? – user3086548 Dec 30 '13 at 15:52
