I’ve been experimenting with the Grove Starter Bundle and a Netduino. I’m pretty impressed with both the Bundle and the Netduino, and I’ve written a series of articles documenting how to use them to build a timer for a plant light.
While the code is specific to the Netduino (which is a .Net Micro Framework device compatible with Arduino shields), the descriptions of the various twigs - especially the LCD and Relay - might be helpful to Arduino users too.
The 3rd article in the series is at gigamegatech.com/2011/01/08/netd … -be-light/. It contains links to the earlier two articles.
