A relay module is a device that allows an electrical circuit to be controlled by a switch. It consists of a coil of wire that, when energized, creates a magnetic field that activates a switch. The switch can then be used to control an electrical circuit.
Relay modules are commonly used in electronics projects to switch electronic devices on and off. They are especially useful for controlling devices that are powered by high-voltage AC circuits, as they provide a safe way to control these devices using lower-voltage DC circuits.
There are many different types of relay modules available, each with its own unique features and applications. When choosing a relay module for your project, it is important to select one that is compatible with the power requirements of your device and that has the correct number of channels for the number of devices you wish to control.
