arduino powered mod
« on: December 14, 2014, 10:30:52 PM »
I'm planing on building an arduino powered vv mod using a n channel MOSFET that gets turned on and off by the arduino's pwm cababilitys basicly making it pulse till its at the bright voltage. Also. I will use one of the analog inputs that for it can tell what the voltage is to begin with. Does anyone know of anyone who has done this before? Idk how break does his or if this how he does his or not.

Yes several people here have done mods like you are describing.  It's not difficult to wire and fairly easy to program, but there's some tricky things you have to do to measure voltages and currents, mainly it's a matter of timing and filtering.  Also you need to do some math in code to work out RMS data points. 

You may want to use a MOSFET driver rather than trying to drive the MOSFET directly off one of the MCU's I/O pins.  MOSFET gates have a good amount of capacitance and you want to avoid driving capacitive loads directly off an I/O pin.  It's hard on the MCU and in extreme cases can cause spurious resets.

Thank you Craig for your response. Do you have a link to some build logs for these? I'm just wondering to take a look at them.

Don't have any links off-hand, I'd have to search the forum posts same as you, maybe someone else can find them for you.
