Sending and receiving radio signals broadcasts to all devices that have radio capability.

A radio channel can be set which means that only devices on that same channel will receive those broadcasts.

Gpio pins - General Purpose Input/Output (GPIO) pin, is a programmable pin found on microcontrollers and other digital devices
Circuits - is a complete path that electricity can travel through. It’s like a loop that lets electric current flow
Wireless - the transmission of data between devices without using physical cables or wires
