In the past few months, we have covered various solutions that can make your home smart. The nextBulb happens to be a smart light bulb that knows where you are and turns itself on when your phone is in range. nextBulb uses Bluetooth (iBeacon) technology to measure the distance from your smartphone. The companion app allows you to organize your light bulbs and assign them into different rooms.
The app also lets you change the color of your light or put your light bulbs on a schedule. You can find this interesting project on Indiegogo.
