I am using IDE 17 have the lcd and Wishield both working seperately and am using interrupt set to pin 2. The problem comes when I add line LiquidCrystal lcd(4, 3, 8, 7, 6, 5);, then it no longer tweets.
I also have 3 sensors hooked up. I didn't think it was a power issue as when I comment out the LiquidCrystal line and leave the lcd on, it still tweets, but it may be a power issue.
Any suggestions are welcome. Thanks.
