Hi Everyone,

This is my first Netduino project. I built a popup skeleton and was controlling it with some old X10 stuff. You can see this phase in action in this video. But I wanted to add LED eyes and maybe some sound. So I ordered the Netduino+ a few weeks ago.

So far I have the following features working:

1. The Netduino is setup to act as a web server. Nothing special, the single page it serves has one button that, when clicked, runs the popup cycle. I'm going to use my Andriod tablet on Halloween to scare people when they walk up.
2. The popup cycle follows these steps
A. Signal the external relay board using digital I/O #2 for 2 seconds. The external relay board sends 24vac to the automatic sprinkler valve. The sprinkler value allows air to flow from a compressor into a modified screen-door closer.
B. Flash the LED eyes using digital I/O #0 and #1 for 8 seconds.
C. I plan on adding lights that will shine on the skeleton and some sort of audio laugh-track.
3. Every minute, when the popup cycle isn't running, the LED eyes flash in a few different patterns.

In this video you can see the flashing eyes.

Very cool! I used to build halloween props as well, eventually may revisit them and add microcontroller magic.

Thanks, ItsDan! I added audio yesterday by modifying a "spooky doorbell" device I picked up at a local Halloween store.

Bill, that's startling :) Awesome for Halloween...and the sound helps add spook effect. Oh man. Halloween. What costumes and projects will folks build this year? I'm excited to see! Chris

Just out of curiosity, what kind of external relay component did you use? I've worked with Phidgets before, but I don't recognize the one in the picture.

I've been looking for something that is reasonably priced to control a Christmas light display with a Netduino Plus. It looks like this may be a winner. I completed this project (http://channel9.msdn...Show-Version-20) last year, but the Phidget relay module was too expensive for what it does.

Thank you

Hey Bill I realize this an old post but can you share how you hooked up the relay board to your netduino. I am planning on using the same board in a project (but the 16 channel one). Are you just plugging the pins into the digital outputs of the netduiono ?
