How do I connect and control a One Channel Relay?

To connect and control a One Channel Relay, you typically need to provide power to the coil and connect the controlled circuit to the relay’s switch terminals. The coil is usually driven by a low-power signal, such as a digital output pin from a microcontroller or a relay driver circuit. When the coil receives the appropriate signal, it activates the switch, which completes the circuit and allows current to flow through the controlled device. The specific wiring and control requirements may vary depending on the relay module you are using, so it’s important to consult the relay’s datasheet or documentation for the correct wiring and control instructions.
