MP3 Switch On/Off Conundrum
This problem relates to a table-top fairground carousel.
The carousel plays music as it rotates and this was provided by a tape unit until 30 years of use saw its demise. I decided to fit a MP3 player that was small enough to fit into the limited space. A suitable music track was downloaded and the unit was tested as working fine. The snag was that the music was triggered by a pressure switch which was impractical for the setup. To overcome this, I cut off the pressure switch and replaced it with a 6V relay. Power up MP3, switch on relay and all will be fine - or so I thought.
If I connect the switch wires directly, the MP3 plays. If I switch it via the relay, there is no sound at all. The relay checks out as working correctly.
Will somebody suggest where I am going wrong or if there is an alternative to a relay? Bear in mind that my electronics knowledge would be regarded as dim by a fencepost. Help!!
Is this a good question?
