I just got the temp probe working and want to connect it to my Ethernet shield via the Leonardo. After several failed attempts I asked a friend to help. He sent me a sketch that works great. The problem I have run into with it is I need to have the Serial Monitor open before it will display anything on the web page. I would like to make this a stand alone project for remote temp sensing. Once I enable the Serial Monitor everything works great. If I remove all of the Serial print statements in the sketch, the page just keeps saying searching and finally times out. The only other board I have is the nano but no way to use it with the Ethernet shield directly.
Is this a known problem with the Leonardo? I know every time I load a sketch, it changes the com port!!
Thank you for any information about this!
