Hi All, I'm a newbie to arduino & need to get a feel whether or not this is an achievable project, heres the situation I have & possible solution i'm thinking of: I need to develop a variable amplitude waveform generator (sinewave,triangle,square wave & possibly even a pulse generator too if time allows), at the moment we are using an agilent function generator that only goes between +/-5V amplitude with a wideband amplifier attached to the back end to give the amplitude. I'm looking to use an arduino to control the small front end signals & maybe use either some power mosfets on the back end or possible an op amp to boost the signal to around +/- 50 V but combine it all into one nice box which does it all. Does this sound feasible & how would you go about it if you were to design a project like this???Would I need an arduino due for better resolution??currently experimenting with an uno... I look forward to your thoughts & responses.
