+Greenhouse Shield for Arduino
+Copyright 2010 by Bdale Garbee, released under the TAPR Open Hardware License
+
+This is a board my son Robert is building to monitor and control conditions 
+in our back yard greenhouse.  The objective is a "shield" for an Arduino
+Duemilanove board, with the following features:
+
+       - temperature sensor                            MCP9700A
+       - light sensor                                  PDV-P9007
+       - humidity sensor                               HCH-1000 + TLC555
+       - i2c real-time clock                           DS1307
+       - i2c non-volatile memory for data logging      24AA1025
+       - 4 relay-switched mains (110 volt AC)
+               - electric heater (high current!)
+               - electric fan
+               - hydroponics pump
+               - spare
+       - spi TeleDongle interface for RF link
+               http://altusmetrum.org/TeleDongle
+
+The idea is that we log temperature, light, and humidity every so often to
+the non-volatile memory with timestamps.  On each sample, we check current
+conditions and turn the heater on if it's too cold, and the fan on if it's
+too hot.  The hydroponics pump gets turned on and off on a regular schedule.
+And the RF link provides a mechanism for remotely downloading the logged data,
+changing setpoints and schedules, manual override, etc.
