Can anyone tell me how to make a device that will play a song from an iPod whenever someone gets close to it? Answered
I am an art student looking to make a project that will "scream" in fear (play a pre-recorded sound) every time someone gets close to it. So far all I have is a proximity sensor. I sent an email to my teacher and he suggested having the track play as a loop and then using a transistor and a relay to switch the signal through a modified audio cable. I haven't been taught how to do any of this and my teacher is not responding to my emails and I am running out of time. Please help!
