It is an easy fun project that you can build in less than 45 minutes and helps you remind to turn off the lights. Save Energy and Save yourself from your Parents.

Step 1: STEP 1 : BUILD Lego BRICK STAND

Step 2: STEP 2 : APPLY ALUMINIUM FOIL

Place a piece of aluminum foil on switch cover and wrap another piece of foil on to the switch (Make sure that piece of foil on switch is long enough so that when the light is turned on, it touches the foil placed on switch cover).

Step 3: STEP 3 : BUILD THE CIRCUIT

Using littlebits Power + Makey Makey + Bargraph + Servo Add Servo Accessories & Alligator clips.

Step 4: STEP 4 : ATTATCH ALLIGATOR CLIPS

Attach the other end of alligator clips to the aluminum foils placed on the switch and the switch cover. Cover the circuit with the monster head (template A). Attach the servo with mechanical arm as seen the picture using tape.

Step 5: STEP 5 : TEST CIRCUIT

Now, when your light is in the on position, the circuit will complete and the servo will block your door with a sign that reads "Turn the lights off." Never leave your light on with Light Saver!
