This block is fun. It detects motion and can tell other wireless blocks to react. When tilted from side-to-side, it sends a message to turn things on and off. Use it on your door handle to set off an alarm or shake it to flash your LED Light.
Each wireless block has a Bluetooth chip and rechargeable battery inside it. Simply recharge your block with a Micro USB Charging Cable. Bluetooth Dongle for laptop and charging cables not included.
