The littleBits Bluetooth Low Energy Bit (marked "BLE" on your Bit) is the easiest way to control your inventions wirelessly, from any smart device (like a phone or tablet). All you need is the littleBits Invent app and this Bit to move motors on wireless vehicles, or trigger buzzers for pranks. You can also use your circuit to control functions on your device, like triggering the camera to take a picture.
The Bluetooth Low Energy Bit can send and receive a signal from your smart device using Bluetooth Low Energy wireless technology, up to a distance of about 80ft (25m) indoors. To use the Bluetooth Low Energy Bit, you first need to connect it to your smart device (smartphone, tablet) through the littleBits Invent app. Check your device's compatibility at littleBits.com/app. Click the arrow to the right to learn what you can do with this Bit!

Controls range from simple buttons and dimmers to accelerometers. You can communicate with up to 2 Bluetooth Low Energy Bits at the same time.
