There are hundreds of tutorial available on how to use a "relay module" but I could not find a good one that shows how to use a Relay and not a Relay module. Download . Hi guys how are you ?I hope you are fine !Are you looking for making a relay board yourself , then your in right place.today i will show you how to make a Diy relay modulethat can be used any purpose . Make sure they are well isolated from your DC boards and double check the connections going to the relays. The thermal relays mentioned below should be excluded from this description. This makes it easy as Arduino can power up the relay directly. You can also notice a diode connected across the coil of the relay, this diode is called the Fly back Diode. Free Schematic Diagrams. Includes back-EMF protection and LEDs so you can easily see the state of the outputs. Circuit Diagram: Atmega328P Pins Connections. Coming to the design of the circuit, it is very simple as we used a 5V relay module … The figure shows the switched connection configuration for the relay at rest. Use these Control4 DIN-Rail 8-Channel Relay Switch wiring diagrams along with the DIN-Rail 8-Channel Relay Switch Installation Guide (ctrl4.co/8chrelay-ig) to install DIN-Rail 8-Channel Relay Switches. Relay module for Arduino is one of the most powerful application for Arduino as it can be used to control both A.C and D.C devices by simply controlling the relay by giving 5V. In this project, there are three main components used an Android Blynk app, Wi-Fi Node MCU and 4 Channel Relay module. The 8 channel relay module has its own optocoupler also called opto-isolator, photocoupler or optical isolator. The six pins on the left side of the relay module connect high voltage, and the pins on the right side connect the component that requires low voltage—the Arduino pins. In summary, small currents and voltages provide greater current and voltage control. 5V 2-channel relay module; 5V 1-channel relay module; 5V 8-channel relay module; 3.3V 1-channel relay module; Relay Pinout.
