Netduino 3 and Electronic Brick of Relay

01 August 2015 - 08:01 PM

Trying to figure out how to plug things.


I'm using this relay http://www.robotshop...k-5v-relay.html


Let's call the screw connector : Connector 1

Let's call the white 4 pin connector : Connector 2

Let's call the black 3 pin : Connector 3


I want to use it to make a 12 volt valve work.


I striped red and black from a 12 volt adapter pluged in a wall.


Black and red goes to Connector 1 (tried both NC and NO)


Then I'm not sure if I'm supposed to plug netduino digital pin to Connector 2 or Connector 3, and output 12 volt from Connector 2 or Connector 3.........


I've tried both, didn't work.


Of course I've read the datasheet but it's not detailed enough for me and can't find any project with this exact relay.

my code :

static OutputPort relay = new OutputPort(Cpu.Pin.GPIO_Pin0, false);

How do I wire this relay ?


Outdoor project, 70 feet, 5 walls and a shed.

11 May 2015 - 08:28 PM



I'm looking to do an outdoor project that needs to receive the signal from about 70 feet from the home router. Also, there are multiple walls (5?) between the router and the microcontroller.


Can it work with the Netduino 3 built in wifi or do I need to add an antena ?


The Netduino will be inside a shed.
