Thank you all SO much. I have looked at what seems like 1000s of switch things online and I couldn't find anything like it.

 

Hi,

I am building this prop as a birthday gift for my daughter. I am using an Arduino Pro Mini for the brain. All the electronics are behind the board, the components on the front, other than the toggle switch are dummies. My question is, to all the electronics people on the board is, does anyone know what the piece in the red circle is? I have identified and installed all the other parts. I have wired up the Arduino behind and all is working well. All that is stopping me from being done is to find that ONE component! The birthday is approaching, if anyone knows what that thing is, I would appreciate the help SO MUCH. 

OK, thanks 

I was thinking that a switch and a bit of code might work. I could use another pin for the headphone sound and use a switch to choose which pin I use for audio. In "speaker mode", it would go through the amplifier, in "headphone mode", I would use go through a 10k resistor to a headphone jack.

OK, thanks very much for the help

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. It's a great little board and it is working wonderfully. I am using a little 0.4W 8oHm speaker and the breakout board for amplification as I have a very confined space to fit my project into.

Would it be possible to introduce the headphone jack into the circuit before the amplification board? Obliviously, I don't want to amplify the headphones, just the speaker.

Your help is very much appreciated.

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

 

Hi,

Could someone point me to a simple circuit for how to use the closed circuit 3.5mm jack to interrupt a speaker? 

Thanks

Hi,

Yes, mono. Thanks so much for the help

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.

 

I am a bit of a noob, so I have a very basic question  

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 https://www.sparkfun.com/products/11044. I have a 10k potentiometer on the Amp board to adjust the volume. It is working very well. What I was wondering is, is it possible to add a headphone jack for the sound that when the headphones are plugged in, redirects the sound from the speaker's pin to the headphone jack automatically?

Thanks  

Yes, my daughter is a huge fan of the show. I am building the prop EMF detector so she can go "demon hunting".   

Thanks so much for taking the time to help me. I really appreciate it! 

Thanks! 

I am also trying to make out what they say on them. The grey ones look like 10nK (?) Not sure about the yellow ones.

Hi,

I am using an Arduino as a basis for a prop I am recreating. I was hoping that someone here could help me identify a part from a photo so I can track them down online (or something very similar).

  Many thanks
