2 Relay Module Arduino Datasheet

The example we ll build shows how to control a relay module with an arduino and a pir motion sensor.

2 relay module arduino datasheet.

It can be controlled directly by microcontroller raspberry pi arduino 8051 avr pic dsp arm arm msp430 ttl logic. Then you can see the led cycle between on and off. Oct 06 2018 10 19 am by khalidoos am newbie to arduino i have 2 relay module opto isolated and arduino uno i have written simple program to control relay i have connected vcc to 5v from arduino and gnd to gnd from arduino also jd vcc and vcc are short circuits. Then you can see the led cycle between on and off.

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. Dc 30v 10a ac 250v 10a. 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. 2 channel relay module with optocoupler low level triger expansion board which is compatible with arduino.

Control the 2 channel relay module to on or off. 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 module board be able to control various appliances and other equipment with large current. Arduino 2 channel relay.

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. Arduino and 2 relay module oct 06 2018 08 59 am last edit. 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. This is a 5v 2 channel relay interface board be able to control various appliances and other equipment with large current.

Ky 019 5v relay module. Upload the sketch 4 channel relay demo to the arduino uno or atmega2560 board. The actual figure is shown below. Hot deals from.

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. Songle 5v relay datasheet. We make a brief introduction to the relay module and build a simple project example with the arduino. By the end of this tutorial you should be able to control any electronics appliances with your arduino using a relay module.

In2 17 in1 18 step 2.
