Garden/shrub watering system

To keep my wife happy in her gardening, I have put together a PICAXE-based watering system controller that might be of some interest. The system has been dry-tested but, since our morning temperatures here in Colorado are still below freezing, I will have to wait for a month or so to actually water something!

Have a look and let me know what you think.

Interesting project.
One thought pops to mind. You may want to incorporate a temperature sensor to find out if there is a frost or not. Saves bursting pipes etc. :eek:. The DS18B20 is very easy to use, just the simple 8-bit temp. info is all you'd need.

Not sure what the climate is like in Austin, but here in Christchurch, NZ in the spring after the majority of frosts are gone, a few more can still 'sneak' in.

Also, would you post your code? Either here, or on 'net.

my 2c worth. Well done. Looks good.

The code is here: http://www.scottsweb.org/the_code.htm

There are a number of possibilities I am considering...but the I2c is the most interesting but I am still trying to get my hands around this.

The problem with frost/freezing is that the lines and valves can burst if there is any water in them..they have to be blown out to prevent freezing/bursting..

Scott,

as this is a site for finished projects, can I respectfully suggest that you actually post the program code and maybe a photo here on the forum.

My reasoning is that over time links to external websites get broken and the information is lost to forum members.

with respect to i2c, sugegst that you download the i2c tutorial from here: http://www.rev-ed.co.uk/docs/axe110_i2c.pdf as a starting point.
There are also many i2c based exampled for RTC's, IO expanders and other chips hidden away of this forum. Searching can find all sorts of gems.
