Hello, im working on a project where i need to hook up 2 speakers to an arduino duemilanove, but me having no knowledge on electronics, has no idea how to do it.
The project is basically making something like this http://www.instructables.com/id/Arduino-Laser-Show-with-Full-XY-Control/
but with smaller speakers, and possibly less materials.
i will be using two 2 watt speakers that i need to be able to control with the arduino. Im kind of confused on how to ground everything, because i really dont want to fry my board a day after i got it.
I am using a setup like this so far but have no idea how to put two speakers on it http://www.bit-101.com/blog/wp-content/uploads/2013/05/motorcontrol_bb.png
