I'm a complete noob to netduino and the whole microcontroller and embedded electronics arena.  I purchased a Netduino Go and hooked it up to a Nwazet Relay and I'm able to turn some christmas lights on and off, which was pretty exciting!


Now I'm looking to expand on my project and I'd like to control 3 different AC loads independently (kind of like a traffic light scenario) where any combo of the 3 lights could be on or off at the same time, or turn them on/off in sequence, etc.


What's the easiest hardware path forward for this?  I know I could buy 2 more of the Nwazet Relays and use up 3 GO ports, which has been my current plan.  The Nwazet relays are nice, but they're $14/each and you have to solder everything yourself.


Then I found this pre-assembled relay board on Amazon that already has 8 solid-state relays on it, for only $23 !


SainSmart also makes other versions of relay boards with varying numbers of relays included.

Does anyone have experience using these SainSmart boards with a Netduino GO?  I'm assuming I'd need the Shield Base module to interface with it, but after that I'm not sure how to wire up everything (SainSmart --> Shield Base)....


Any recommendations?

I haven't done this myself, but you could use one of these:http://www.ghielectr...log/product/405 to break out the pins from the GO socket to the pins on the relay board.

I've had great success with the SainSmart relay boards using Netduino+, haven't tried them with the GO.

Also tagged with one or more of these keywords: relay, go
