For example I have a speaker with buttons: volume up, down, play, pause, next, previous. I want to embed into this speaker a blutooth feature to simulate buttons pressing. For controlling I will use a mobile phone (android), controlling application I can create by myself. I have no expierence in electronic, but I can try. Easy solutions would also be wellcome. Are there any easy to integrate universal solutions I can buy?
I also have an arduino (it is too big for my purpose) and can use for prototyping. I have a bluetooth board http://www.bluesoleil.com/products/H0002201304270003.html
