Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation ... With help from a sensor, the composition also "protects ...

The system combines familiar adhesive stickers with electronic components, such as LEDs, sensor circuits ... in four types: LED stickers in four colors, sensor stickers (light, sound, and timing ...

Philips Hue has a new accessory that’ll make it even easier to automate the lighting in your home: a motion sensor. This is, of course, a very standard add-on for home lighting — which is what ...

and after one iteration he settled on a circuit which can provide the board power from a battery or a USB cable, while also managing the battery’s charge. As for sensors, it has a light sensor ...
