By the end of this tutorial you should be able to control any electronics appliances with your arduino using a relay module.

2 relay module arduino pdf.

Connect the signal terminal in2 in1 of 2 channel relay to port 17 18 of the raspberry pi and connect an led at the output terminal. The actual figure is shown below. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. Control the 4 channel relay module to on or off website.

Arduino 2 channel relay. Vcc and com pin is connected to the 5v power supply gnd. A normally open configuration works the other way in which the relay is always open until you send a signal from the arduino to the relay module to close the circuit. Connect the components based on the figure shown in the wiring diagram using m m and f f pin connectors.

Connect the components based on the figure shown in the wiring diagram using pin connectors. Control the 2 channel relay module to on or off. This instructable is for connecting your arduino to a 2 channel relay module and using your sketch to control the switches i bought the 2 relay module on ebay for 9 50 to drive a couple of 240v parts a vacuum cleaner and a rotary engraving tool. 2 relay module interfacing with arduino 2 relay module is an electronic device consists of two relays as its major components.

Then you can see the led cycle between on and off. Vcc pin is connected to the 5v power supply gnd. In2 17 in1 18 step 2. The further detail about 2 relay module interfacing with arduino will be given later in this tutorial.

Microcontroller any compatible arduino 5v isolation relay module m m pin connectors f f pin connectors breadboard usb cable 1. It can be controlled directly by micro controller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic. Upload the sketch 4 channel relay demo to the arduino uno or atmega2560 board. 4 channel relay demo name 4 channel relay description.

Then you can see the led cycle between on and off. Learn how to use relay with arduino how relay works how to connect relay to arduino how to code for relay how to program arduino step by step. This is a 5v 2 channel relay interface board be able to control various appliances and other equipment with large current. We make a brief introduction to the relay module and build a simple project example with the arduino.
