Node.js, Raspberry Pi and irrigation control, Part 2
In my previous blog entry I created a node.js server that accepts a crontab like configuration to turn on and off the virtual irrigation LEDs in a browser. These virtual LEDs are currently hard coded (part of the user configuration that I still need to work on). I've now added the external interface to digital IO in the form of an Elexol Ethernet/UDP IO24 board (an older revision). I think I've standardized on the device interface. I'll need to create a nice Node.js module for the device interface (something new to learn). I hope to create other interfaces to an Elexol USB interface and some Pi direct IO interfaces.
