What is a 5V Single Channel Relay Module? 🤔

A 1-channel 5V DC relay module is designed to control high-power devices using a low-power microcontroller or other control signals. Let’s break down its key components and features:

⭐Channel: The term “1-channel” indicates that this relay module can control a single device or circuit. The relay can turn the device on or off.

⭐Relay: A relay is an electromagnetic switch that allows a low-power circuit (controlled by a microcontroller or similar) to maintain a higher-power circuit or device.

⭐Voltage Rating: The module operates at 5V DC, requiring a 5V DC power supply.

⭐LED Indicators: Many relay modules have LED indicators that show the relay's status (whether active or not).
