Electronics are awesome, and are relatively safe as long as you aren’t pumping too much power through them, but sometimes Hobbyist Electronics simply aren’t enough to cool a room or boil a kettle, and in such times it’s often easier to simply integrate AC devices and machinery into projects. However, while AC devices are typically capable of higher power ratings and inductive loads, they can’t simply be controlled directly with a DC circuit, and this is why Relay Modules are such awesome devices.

Relays like these Single Channel 5V Relay Modules are designed to act as switches, allowing DC circuitry to activate or deactivate AC circuits, with these particular models being capable of up to 5A @ 250V AC. This means that you can use these handy little relay modules to control AC devices and machinery with ease, by simply activating or deactivating the relay switch. These features make relay modules like these the ideal choices for home automation and smart tech’ integration into living spaces – although they’re also just as good for turning on the lounge fan, coffee machine or other devices remotely.

This relay module features the DFRobot Gravity Series PH2.0-3P Port for powering and controlling it, while on the other side of the board there are four screw terminals labelled “NC”, “NO”, “N/A” and “COM”. This is a relatively stock-standard style for relays, although the Gravity Series connector does make it very easy to use with Arduino Boards. However, if you’re not entirely sure of how relays work with their ports, it’s a good idea to brush up on this knowledge, or check out the handy DFRobot Wiki featured below the following table.
