One of the other projects I've been working on is a garden watering timer, the house we bought has a James Hardie system that wasn't working, so I salvaged the (3)valves out of the ground, (the gardens had been redone and the sprinkler ends removed earlier) the control box off the wall, just for the 24v transformer inside it.
A coupla weeks ago I bought a Leostick (http://www.freetronics.com/products/leostick) from the local Jaycar (there is 3 Jaycars equal distance from our home).
I had found a Menu library written to help with devolopment. Link(http://www.coagula.org/content/sites/default/files/source/menu_and_lcd_display.pde)
and adjusted it for my project.

**Note** Manual time runs for 30 mins then turns off
in the photo i using a 16x2 LCD at D7, D6, D5, D4, D3, D2, 3 momentary push buttons at D8, D11, D12, potentiometer for contrast and the the leostick, which has a RGB LED at D9, D10, D13.
so on my to do list was to add a real time clock and connect relays, put it all in a box and set up the pipes / sprinklers.
so yesterday i got a RTC (http://www.freetronics.com/collections/modules/products/real-time-clock-rtc-module) and 4 channel relay board (http://www.freetronics.com/pages/relay4-4-channel-relay-driver-module-quickstart-guide).
i spent all yesterday trying to get the RTC to work for me, but the library's i found didn't function correctly for me.
Tada the RTC finally works for me turns out the Serial baud rate was set wrong on the test program so when i ran in all got was jiberish, until until i set the baud rate correctly and shows the correct values, now i can move forward.
so the Library / Code i used is from here
link found here http://arduino.cc/forum/index.php/topic,57642.0.html.
to set the time / date the format used somewhat gathered from the sketch and the .cpp or .h files
is YYMMDDwHHMMSS , the 'w' is the day of week number 1-7 and i guessing 1=sun 2=mon but don't quote me on that, and put an x at the end as explained in the sketch.
now to make the RTC work with the leostick and the lcd display.
