2 Relay Module Arduino Pdf

2 relay module interfacing with arduino 2 relay module is an electronic device consists of two relays as its major components.

2 relay module arduino pdf.

The example we ll build shows how to control a relay module with an arduino and a pir motion sensor. In this configuration the relay is always closed and remains closed until you send a signal from the arduino to the relay module to open the circuit. Arduino 2 channel relay. The actual figure is shown below.

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. In2 17 in1 18 step 2. 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. 4 channel relay demo name 4 channel relay description.

Microcontroller any compatible arduino 2 channel 5v 10a relay module pin connectors breadboard usb cable 1. The further detail about 2 relay module interfacing with arduino will be given later in this tutorial. We make a brief introduction to the relay module and build a simple project example with the arduino. Upload the sketch 4 channel relay demo to the arduino uno or atmega2560 board.

Connect the components based on the figure shown in the wiring diagram using m m and f f pin connectors. 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. Vcc and com pin is connected to the 5v power supply gnd. Control the 4 channel relay module to on or off website.

Connect the components based on the figure shown in the wiring diagram using pin connectors. Then you can see the led cycle between on and off. By the end of this tutorial you should be able to control any electronics appliances with your arduino using a relay module. It can be controlled directly by micro controller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic.

Microcontroller any compatible arduino 5v isolation relay module m m pin connectors f f pin connectors breadboard usb cable 1. Vcc pin is connected to the 5v power supply gnd. The detail instruction code wiring diagram video tutorial line by line code explanation are provided to help you quickly get started with arduino. Then you can see the led cycle between on and off.
