2 Relay Module Arduino Datasheet

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.

2 relay module arduino datasheet. Upload the sketch 4 channel relay demo to the arduino uno or atmega2560 board. The example we ll build shows how to control a relay module with an arduino and a pir motion sensor. In2 17 in1 18 step 2. 4 channel relay demo name 4 channel relay description.

Arduino 2 channel relay. Dc 30v 10a ac 250v 10a. Hot deals from. The actual figure is shown below.

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. This is a 5v 2 channel relay interface board be able to control various appliances and other equipment with large current. 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.

Control the 2 channel relay module to on or off. Then you can see the led cycle between on and off. Then you can see the led cycle between on and off. 2 channel relay module with optocoupler low level triger expansion board which is compatible with arduino.

Ky 019 5v relay module. Standard interface that can be controlled directly by microcontroller 8051 avr pic dsp arm arm msp430 ttl logic relay of high quality loose music relays spdt. 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. It can be controlled directly by microcontroller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic.

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. Arduino and 2 relay module oct 06 2018 08 59 am last edit. Arduino ky 019 relay module is used to control ac circuits the relay acts as a switch that responds to a signal received from the arduino it has an integrated led that indicates if the signal is high or low. We make a brief introduction to the relay module and build a simple project example with the arduino.

Songle 5v relay datasheet.
