bluetooth module
Short-range radio component
A Bluetooth module is a small electronic component that enables wireless communication between devices using Bluetooth technology.
These modules contain the radio, antenna, and processing circuitry needed to transmit and receive data over short distances: The Arduino connects to your phone through a Bluetooth module.
Hobbyists and engineers add them to projects that need wireless capability without building the radio system from scratch.
