Hi,
I am trying to code for a specific sequence of 6 FSRs inputs that trigger a wifi connection. (once the correct sequence has been received the wifi shield connects to a specific http:// address.
I would really appreciate any help!
Thanks
Dian

int status = WL_IDLE_STATUS;
// if you don't want to use DNS (and reduce your sketch size)
