/*
* ZMHW Project: Map
*
* A device to give you a visual representation of what Monitors
* are active in your camera network.
*
* SteakElectronics, December 2018
* Rare steak, well done electronics.
*
* Based on: telnet client
*
* Requires: UIPEthernet library
*
* Nice to haves in future:
* PWM dimming, after alarms are off, so you know what was recently on.
* Blinking on active alarms, instead of solid light, maybe.
* Faster direct port access than digitalwrite. There are some libraries
* but I don't know if they support the Mega. Instead, I'm going to rebuild the board
* with a led matrix, and then use pwm pins, and I will deal with it then.
* EDIT: instead maybre I'll use two 0402 resistors, and make a voltage divider, to allow for
* dimmer led, with hardware instead of software.
*
* Troubleshooting Programming: When connecting, it can take 30-60 seconds
* to speed this up, run the test suite telnet connect and it should connect
* immediately after. The idea is that, it seems to connect as soon as a packet is
* sent from zmtrigger. So send a test telnet packet, then it will connect after.

Telnet client
This sketch connects to a a telnet server (http://www.google.com)
using an Arduino Wiznet Ethernet shield. You'll need a telnet server
to test this with.
Processing's ChatServer example (part of the network library) works well,
running on port 10002. It can be found as part of the examples
in the Processing application, available at
http://processing.org/
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
