Hey Guys,
My Arduino is still running strong with the above sketch, and I had some time at lunch so I knocked up a Shield and sent it of to get fabbed.
It will allow me to keep everything together and a small footprint (51cmx51cm)
It has screw down Terminals for 4 x SSR's and as many Temperature sensors as I want, a pin header for Ethernet as well which supports both
ENC28J60 & Wiznet Chips & 2 pin headers for each pin on the Arduino.
Cheers Rob.
