Turn Off Light From Bed

Well my mom likes to wake me up for school in the morning my turning on my light, and I got tired of being blinded first thing in the morning and having to walk across the room just to turn off the light, so I decided to make a quick way of turning off the light from my bed. This is a fairly easy instructable (i think), i also thought it was quite fun to do. Note: this only works with the flip-style light switch.

Step 1: Materials


old light switch cover

dc motor

project box (i used an altoids tin)

2 momentary push button switches

lots of wire

2 AAA battery packs (I used 1 AA and 1 AAA)

heatshrink tubing

hot glue sticks

a screw


drill (not shown)

soldering iron

wire cutters/ wire strippers (not shown)

hot glue gun

Step 2: The Case

I drilled a hole in the side for the wires going to the motor to go out, then I drilled 2 holes in the top for the wires to the buttons.

Step 3: Build the Circuit

Follow the schematic below to build the circuit. But: DO NOT ATTATCH TO MOTOR YET! just twist the 2 ends together for now. Make sure to thread the wires out of the holes for the buttons before soldering. I hot glued the 2 battery packs to the bottom of the case and hot glued the 2 buttons on top to hold them in place. 

Step 4: The Motor

For this step, I held the motor against the light switch to figure out where to position it and marked with a pencil. now take off the faceplate for the lightswitch. I drilled a hole for the screw to come up to help hold the motor on the plate, then I hot glued the motor onto the faceplate. you may have to loosen or tighten the screw to get the motor to turn off the light efficiently.

Step 5: Final Touches

now solder a wire to each of the ones you twisted in step 3. (there should only be 2, both have a positive and negative twisted together) then thread the 2 wires out of the hole in the side of the case (put a knot on the inside to prevent the cable from pulling out). now solder the other ends of the wires to the points on the motor. now just screw the faceplate back on the wall. finally figure out which button turns on the light and which one turns off the light (I made a label). and test it out to make sure it works.

Step 6: All Done!

below is a video of me using my switch. please comment and rate. I hope you enjoyed this Instructable. thanks for viewing :)

    You can also induce a short circuit to switch off all lights - you just need a plug socket...

    Sounds like you could maybe use the wireless guts of the car to make this wireless too.

    i was going to try and do that but the circuit was fryed somehow and about the only thing i could use was the motors, but if i can find another rc car and some other parts im going to make a second version of this

    thanks :)  and you could probably go to an hobby shop and get a servo instead of that motor btw.

    You could do this with a servo, but please note that it would require modifying the servo or building some more advanced circuitry.

    The servo modding would basically be ripping out all the internal electronics and only using the motor and gearbox. The motor  should be good to run from 4.5-9 volts, but remember that  the output shaft cannot turn 360 degrees and that stalling is bad.

    The more advanced circuitry isn't really very difficult, just more advanced than switches. You need to send signals to the servo which could easily be done with 555 timers. Remember to use 4.8-6 volts.

    That same hobby shop has some multispeed Tamiya gearboxes.....

    i was thinking that too, but i couldn't figure out how to do it, so this was the best i could do

    oh ok, i didn't know thats what they were called. actually i didn't even think about that. thanks for the idea (:

    Ya, the schematic would look like the picture I posted.

    Also, your design shorts itself out... to increase battery life and  safety, I've added a few diodes to my schematic.

    If your not familiar with diodes, they act as 1 way gates. They are polarized, meaning you have to put them in a special way. So, follow the polarity when wiring.

    PS. That's not a motor, that's a servo. Same thing, but servos use gears for more torque, which you need in this situation.
