Hello,
I have a handsfree bluetooth speaker (this one: http://www.ebay.com/itm/Car-Kit-Speakerphone-Bluetooth-USB-Multipoint-Speaker-for-Cell-Phone-Handsfree-/172697080799?epid=1245995877&hash=item28358c53df:g:DQgAAOSwurZZJ9Ok) that doesn't work - ti's doesn't really matter why, but it can't pair.
I took it apart, and I found a speaker (photos in the attachments). The only info is written 8 ohms and 0.5w. Now I found people on the forums asking questions regarding it, but since I have very little background in electronics (mostly from school like 10 years ago - I only remember how to calculate stuff using Ohm's Law, but I never encountered transistors, capacitors, diodes etc.)
I'm not really sure how to connect it to my board - to the digital pins or to the analog ones, and how to calculate the resistors I need. Also if I need something other than resistors, like transistors, capacitors, diodes I would be happy to know. I would be happy to either know the answer, or how to calculate it.
Ohh and one last thing - this is something I do for a music box project (the ones you open and music starts playing) with midi file that (I found tutorials online but didn't do it yet without working speaker) I will convert to tones. I'm looking for some switch to start the music once the box is opened. I found different switches: Micro Switch with Medium Lever, pack of 10 – Kitronik Ltd or Miniature Push to Break Switch, Black, pack of 10 – Kitronik Ltd - is one of them good enough for this project?
Many thanks,
rd
