As a gift krazatchu designed and built an attractive night light that operates when a signal is received from a motion sensor. Although this isn't anything new - there are two points of difference which make this a great project. The first is the housing, the light has been converted from a simple project into an object that wouldn't look out of place in any home. The second is the low-power requirements - the object can operate for several years on standby using one battery, due to the creative low-power circuitry. For example:
Once again this shows what can be done with the Arduino ecosystem. For more information including code and schematic, see here. To get started with your own Arduino-controlled lighting projects, apart from our range of Arduino-compatible boards - consider our RGBLED: Full Color RGB LED Module. They are easy to connect, and you can control more than one by simply daisy-chaining them together.
