At oomlout we do it many times a day, so many in fact it came to a point where we asked ourselves "Can't we get an Arduino to do this?". Of course we can, what follows is how we went about doing it.
With the help of some acrylic, nuts and bolts and a small hobby servo we have made a great little switcher (we're calling it our Servo Switcher - (SESW)).
- No need to mess with any high voltage wiring.
- Switch is still operable by hand.
- Easy to make and assemble
- Simple light switching.
- Can be paired with sensor to make for more complicated applications. (security lights, temperature control on ceiling fans, night lights, the possibilities are endless) (some sensing examples are in a video on step 3 ).
- Wire up a switch to a socket and control anything that has a plug.
If you feel like skipping the building and getting straight to experimenting lovely kits are available from the oomlout.com shop
