I am a bit of a noob, so I have a very basic question :blush: I am putting together an Arduino project that is using a small 0.4 amp 8 oHm speaker and a Mono Audio Amp Breakout - TPA2005D1 board from Sparkfun SparkFun Mono Audio Amp Breakout - TPA2005D1 - BOB-11044 - SparkFun Electronics . I have a …

You need to get a headphone jack that switches when the plug is inserted. These are readily available. Internal contacts allow the circuit to go to the speaker when there is no plug; when the plug is inserted the speakers are disconnected and the headphones connected.

Thanks for your reply. I didn't realize it was so easy. Is that something that is available from Digikey or similar? I've searched but I'm not sure what terms to use. :blush:

One like this should work assuming we are talking mono speaker, mono headphone. [image] 3.5mm Enclosed Socket Get It Fast - Same Day Shipping Price: USD 0.22 http://www.taydaelectronics.com/hugo/A-865.jpg Lefty

Hi, Yes, mono. Thanks so much for the help :smiley:

Hi, Could someone point me to a simple circuit for how to use the closed circuit 3.5mm jack to interrupt a speaker? :blush: Thanks

Think about it. There is a ground on the socket so that goes to one side of the speaker. There are two other connections on the socket. With no jack in they are shorted together with the jack in one connects to the jack and the other is disconnected from the jack. It is this connection that goes t…

Thanks so much for the help, you explained it extremely well. I'll give it a try. XD

Thanks for the help, it it working very well testing with just a speaker and the jack. IF you would have time for one more question, I would appreciate it. For the actual project I am working on, I am using a breakout board from Sparkfun to amplify my speaker https://www.sparkfun.com/products/11044 .…

Not rearly the arduino does not have enough drive to power headphones. These tend to need a seriese resistor to protect the arduino and that might mess up the input to the amplifier.

OK, thanks very much for the help :slight_smile:
