Hello!
If your wife isn’t close to and you get to make the Space Cadet from your girl costume, likely that you leave a little bit of mold. In my case it was simple; Arduino, a motion sensor, led and Visual Studio 2013.
Note: I never tire of repeating how useful that is Visual Micro for creating projects.
Here’s a video of the final result, as the motion sensor “moves” being sent different values for the brightness of the led Strip. This with a 9V battery and then you have to put it in the guise of Space Cadet.
The source code is as follows:

| MMA7660 acc; | |
| int brightness = 0; // how bright the LED is | |
| int ledStrip = 6; // the pin that the LED is attached to | |
| int accelerometer = 13; // the pin that the accelerometer sensor is attached | |
| int fadeAmount = 5; // how many points to fade the LED by | |
| void setup() | |
| { | |
| acc.init(); | |
| pinMode(accelerometer, OUTPUT); | |
| } | |
| void loop() | |
| { | |
| static long cnt = 0; | |
| static long cntout = 0; | |
| float ax, ay, az; | |
| int8_t x, y, z; | |
| acc.getXYZ(&x, &y, &z); | |
| analogWrite(ledStrip, brightness); | |
| brightness = z; | |
| if (brightness == 0 || brightness == 255) { | |
| fadeAmount = -fadeAmount; | |
| } | |
| delay(30); | |
| } | |
