Thank you for the info. Can we please focus on the question I asked in reply #5?
for some reason when I try to send the "We're closed!" tweet, it gets hung up in the sendNTPpacket() method at the Udp.endPacket(); statement.
Part of the original problem that caused me to write this post still exists. The sketch hangs and I don't understand why. I'm very new to Arduino and was never a particularly good coder. For right now I want to focus on the broken code. I'll get to the inelegant code later.
