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
(a small video of it running a demo program (ie. light switch rave)
Step 1: Parts & Tools
Option 1: Purchase a lovely kit from oomlout.com
- kits with all the acrylic, bolts and servo motor are available from oomlout.com's web shop (here) ($20 or 3 for $40)
- Mini Servo Motor - A small servo motor, these are available in many different power levels, but you will be requiring one of the stronger ones. We use (this one) (shipped from hong kong so can get quite pricey)
- 3mm x 10mm bolt (x3)
- 3mm nut (x2)
- 3mm locknut (x1)
- 3mm washer (x3)
- 5mm washer (x4)
- 6-32 x 1.25" machine screws (x2)
- Cut Your Own (Scroll Saw) -- Download the scroll saw pattern (03-(SESW)-Scrollsaw Pattern.pdf) glue it to a piece of 3mm Acrylic, cut and drill
- Cut Your Own (Laser Cutter) -- Download (00-SESW-Parts File.eps or .cdr) and cut it on your laser cutter using 3mm acrylic
