I have built using the code on this page http://kellykeeton.com/2013/08/06/webpower/ a cool little relay switcher. Now, am hoping to use/add more sensors such as temp and pressure. The Uno memory is full so have bought a mega. In the sketch is gives some comment for changing to a non Uno build but I am stumped.
Any ideas from the pro's here to convert the sketch to running on a mega? My limited reading says uno and mega sketches are largely interchangeable if simple? Cheers for any thoughts
