==Todo==

* Get a better casing
* Integrate with TISSEO(?)

==Nanode code==

https://github.com/techinc/SpaceButton

(and EtherCard fork)
https://github.com/techinc/ethercard

The code uses DHCP to obtain an IP address and
find a gateway.

==Wiring==

The button is a circuit breaker. Connected to pin 3, it pulls
this input pin to ground when not pressed.

The code enables the internal pull-up resistor, so no external
one is needed.


The LED is connected to pin 5, also using a pull-down circuit.
(So the led should be *on*, when pin 5 is low.)

==Troubleshooting==

The LED blinks:

* every four seconds: No link
* every two seconds: No DHCP
* every second: No DNS
* twice a second: Changing the space state, but no response yet from the server
* two seconds on, two seconds off: 'upstream' space state unknown.

==Power==

The nanode is now powered through a USB-port.

DO NOT power it using 9V. There are some issues with
the voltage regulator (which is not used when fed
through (5V) USB.)

== Notification App ==
An Android app is available to monitor the current state of the space and notify when it changes.
