If she also happens to stumble upon some furniture pieces in the process it makes it even more fun.
Just kidding, engineers don't have girlfriends.
Problem 2 was solved by having a remote control for the light, on the nightstand.
|Every person should come with a remote|
This turns on a lamp behind the bed. The lamp was turned over so it only produces a diffuse light:
|Looks nice, when it's not raining|
The motion sensors turn the lights on when one someone steps near the bed (or gets out of it) and the lights stay on for about 20 seconds.
|LED strip going around the underside and one of the motion sensors|
Total cost of the project should be less than 25 USD/EUR:
- LED strip - 5-15$.
- power supply - 1-5$, unless you already have one 7,5-12V supply around
- motion sensors - 1-2$ each
- Darlington power transistor - <1$
- cables, tape, time
