Energy-Saving Light
![energyLight.gif](/proxy/?url=https://content.instructables.com/FWS/D3C3/H0OJ0X2U/FWSD3C3H0OJ0X2U.gif&filename=energyLight.gif)
In the spirit of Earth Day, I have created a revolutionary new energy-saving lighting solution that is only ever on when your eyes are open. This is remarkably more efficient than normal lighting that remains on, even when your eyes are shut. Using my device, you get light when you need it, and darkness when you don't. This is not only beneficial to you and your energy bill, but great for mother Earth.
This device was made as part of my ongoing effort to use less energy, reduce my footprint, and prevent climate change. I foresee similar technologies being implemented in televisions, computers, and electric cars. I am confident that future generations will thank me for this innovation.

Build the Arduino project board as seen here (minus the 9V battery clip). Alternately, you can check out the Hackduino project for something similar.
Wire two 9V battery clips in series to create a +/-9V power supply.
Looking at the wires from the battery clips, connect the single red wire to the +V input on the Arduino project board. Next, connect the red and black wire junction to the ground input on the Arduino project board.
Solder a 6" green wire to one of the outer pins of the female socket. Solder a 6" black wire to the pin next to the green wire, and a 6" wire to the pin next to the black wire.
Solder the other end of the socket's green wire in line with the single black wire of the 9V socket supply. Solder the black wire in line with the center point of the two 9V sockets. Lastly, solder the red wire in line with the singular red wire (that is also connected to the voltage input on the project board)
Connect 6" green wires to pins D9 and A1. Also, connect two extra 6" black wires to ground.

If you have not done so already, plug the socket from the project board into the male power headers on the EMG board. Make certain that the green wire aligns with V-.
Next, plug the green wire from pin A1 into Vout socket and one of the black wires into the ground socket on the EMG board.
Finally, connect the green wire from pin D9 into the 5V socket on the fan controller, and the black wire into the common socket.

Plug the wires into the EMG socket. It is good practice to plug the ground terminal from the jack into the reference socket.
Write down which color wire is associated with which connection. This will be important later.

To use it, you need to attach some electrodes to your face. Place one under your eye, one to the side of your eye, and one directly behind the ear.
Connect the red cable to the one under the eye, the white cable to the one next to the eye and the black cable to the one behind the ear.
Caution!!! Connecting your face to a DIY device that is plugged directly into the wall is a terrible idea. This Instructable was for entertainment purposes only. You should never replicate this.
