Can Arduino produce 4 separate Sine Waves simult..

hi everyone,

i'm getting started hacking arduino, , have several project ideas.  one i'd explore requires outputting 4 separate sine waves, @ different frequencies, simultaneously.  i understand i'd need output square waves, , smooth them out external filter, i'd control on shaping each of waves.

primarily, though, i'm hoping chip has enough horsepower perform task.  if not, i'm sure accomplish similar using 4 separate uc's, 1 each output, i'd love make clean , require 1 processing unit.

also, have experience using lasers photovaristors?  i'd modify sine waves characteristics subtly manipulating amount of laser light input receives, not sure if standard photo components work fine laser light.

thanks!

hi diggum ,
this depends on maximum frequencies need.
