SPI Module of Arduino. To find out which is which, use a hrs44h. WhatRoughBeast 49k 2 28 Skip to main content. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. If you don’t have somebody local to you to help you through this project, you are better off with the pre-manufactured module.

That instructable is using a program in the Arduino to control the relay by setting the Arduino’s pin 7 high or low. The VCC input provides power for the drivers and the relay coils. These ICs are driver chips, and they are what actually drive the relays. The resistance between each of these pins and any of the other three will be infinite.

Thus a small sensor circuit can drive, say, a fan or an electric bulb.

There are many questions here dqtasheet on that topic, so no need to repeat the details in this answer.


What you have in your picture is a plain old relay. The relays in the link you provided do not have a Vcc connection, and they have only 5 pins. Arduino based GPS receiver. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. Virgin Galactic — Commercial Space Flight.

What’s missing? Tell us about it.

The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. The output section consists of contactors which connect or disconnect mechanically. What is Web Browser.

You aren’t going to be datassheet to drive this relay directly from the digital output of a microcontroller. Sign up or log in Sign up using Google. A simple low side NPN switch is usually the easiest way to control a relay from a digital output. This guess is based on the fact that there are two of them grouped separately from the others. Sign up using Facebook.

You should not attempt to drive the relay directly from a microcontroller output pin, as they can’t provide enough current – you would use a micro output pin to control a transistor, which in turn would drive the relay. They are often used to interface an electronic circuit working at a low voltage to an electrical circuit which works at very high voltage.

By using proper combination of contactors, the electrical circuit can be switched on and off.

As such, there is often a larger physical distance between these two sets of pins. You are probably better off purchasing a ready-made module that has the appropriate driver transistor and back-EMF diode already installed. Guessing from the layout of the pins shown in your picture, the coil pins are the two at right. All you have there is a base relay.

Choosing Battery for Robots. And I have no idea why your module can run without connecting ground.

บริษัท อีเลคทรอนิคส์ ซอร์ซ จำกัด

This high-density System-in-Package SiP integrates controller, power switches, and support components. You have made an understandable mistake. Jun 1 ’15 at This voltage is called the operating voltage. Wolfe Jun 1 ’15 at Interface GPS with Arduino. Here’s your relay’s datasheet: Choosing Motor For Robots. Sign up using Email and Password. Sc5v you have a part number?

Olin Lathrop k 30 I have googled with first result as a part’s datasheet with exact pinout. Relay is an electromagnetic device which is used to isolate two circuits electrically and connect them magnetically. If you don’t have an Arduino, you obviously don’t have an Arduino pin 7 to drive the relay. The NO pin will have infinite reistance to all other dataasheet.
