Introduction: 12v 8 Channel Relay Module is an very useful board for any Electrical Project. It is a little box that enables you to control things such as lights and motors without the need of having them permanently on or off. Plus, you can use a single module to control as many eight devices, which is super practical. Every apparatus is connected to a relay of its own, so there are multiple devices and they will not hinder each other. It means you can juggle multiple projects without getting them mixed up.
What is really cool about this module, besides the on-board relays supporting a lot of power. They can be used with high electricity consuming devices (e.g. water pumps, heavy lights). So you are free to build projects that needs more power. It can also work with small computers such as Arduino or Raspberry Pi. These are actual computers you get to control everything with, and they help convey your ideas simply and effectively.
There it is, the Simpliest & Fun to use 12v 8 channel relay module! You might consider it pretty basic since there are just eight places to connect your devices. In addition, there are four control pins to power the module and also control relays. Jumper wires can be used to attach the module to your microcomputer and write a little code which will switch on or off the relays as per need.
For instance, you can program your Arduino so that every device will be switched on for couple seconds at a time. This allows you to determine how long each device is available for use. Every relay has an LED light by it. When you see the LED light on, that means that machine is working and it has been startup. If the light is off LED is not lit, it means that this device does not work now. This helps in identifying which devices are on and off at every point of time.
It's just brilliant for anyone who likes to work with their hands and experiment in electronics at the same time. You can make some awesome projects like smart gadgets which are able to perform multiple activities or robots that have mobility with this module. You can even remotely turn off and on your devices or use their sensors to auto-configure them based on what context they are in.
Like you can control a robot arm with multiple motors using this module. This makes it possible to control the arm and perform various operations. You can also use it to run a greenhouse with extractors and sensors that increase efficiency of growing plants. This further can assist you: a) to establish full security support including Alarms and Cameras or b) make your living smart with Features such as Smart Lights, Curtains even ACs. The choices are limitless!
This was only just a simple example of when you might want to use the 12v 8 channel relay module, I would instead suggest purchasing it and trying for yourself if needed which can be found at most local electronic stores both physical or online. Its a well know and quite cheap module that can really benefit your DIY projects and learning you have. It is common because it is commonly found and serves many purposes There are also many tutorials and examples online that give you the basics for using the module with specific microcontrollers, sensors or actors.
