How do I control power output of 120v electronics with arduino?
I have a device with a motor that my killowatt measures at 120v and at most .220ma. I wish to use an arduino uno to control its strength (reducing it down to maybe 25% at times). What is the best way to go about this? I have seen many different tutorials with different methods. I would rather not cut any of the cabling or open the device.
A motor shield on ebay seems to be the easiest way so far from what I can tell, although there does seem to be a lot of different options for h-bridges. Can someone point me to some good information or tutorials that would be the most effective for this type of power requirements?
Thanks in advanced.
