Thank you all for your input.
One last question:
If I can't pulse a relay, is it feasible to pulse a bunch of MOSFETs? The data sheet at sparkfun says the switching delays are < 1us As long as my pulse period is in the ms order of magnitude than I should be fine, shouldn't I? I don't see propagation delay having a measurable impact here... Just need to make sure to have flyback diodes, right?
Again, my experience with electrical stuff is all theoretical digital logic stuff, so your input is appreciated! This is what happens when a code monkey tries to actually make something
