During the easter my daughter and my sister were growing some garden cress. However, due to our lack of attention, they were constantly running out of water. And died, much to my daughters  dispair.

But that got me thinking. Why can't I use a Netduno to water the cress? I've already figured out how to measure the moisture, so that's not a problem (use 3.3V to an analog input, it's dry if it gets below ca. 40%).

And I got myself a small motor, like this: http://www.ebay.com/...984.m1439.l2649

... for water supply and I want to run it from my Netduino.

I'm not that good with electronics, so how can I achieve that using the simpliest method?

I dug up one of my Netduinos again after several months of absense (we've been moving, and therefore quite busy). I wanted to measure "weatness", so I started by writing a very simple app, just reading input 0, debug.print it, sleep(100) and repeat.

However, it didn't run. The last time I used Netduino I upgraded the firmware on the other one, so I figured I had forgotten to flash this one. A quick check using MFdeploy confirmed that (this one was using RC3).

So I followed the description, and touched the erase-plate and power cycled the netduino. But now the blue light stays on, and my computer does not recognize it anymore. I feel like I've tried everything, but it still won't happen.

What can I do?
