As the title suggests, I am trying to make a vibrational transducer vibrate with changing amplitude according to an analog pattern at fixed frequency. I have been attempting to learn this for more than a month now and I am still utterly confused.
The closest I came by can be found http://bdml.stanford.edu/twiki/bin/view/Haptics/VibrationImplementation.html
It gives details of the op-amp circuit that connects to the transducer. But whatever comes before it, the DAC circuit and whatnot, I have no idea how to accomplish.
If the analog signal (amplitude VS time) I want the transducer to mimic is analog form, why did his circuit have a DAC circuit in the first place? Isn't it analog already? And I can't figure out how the binary numbers come into play.
I know my project sounds really simple but it someone can give me some directions and explain some of the things I need to do it would be awesome!!!
Big thanks in advance!!!!!!!!!
