Nanode code
https://github.com/techinc/SpaceButton
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 by means of a
pull-down circuit.
Power
The nanode is now powered through the USB-port on the wireless router.
DO NOT power it any other way, there are some issues with the voltage regulator (which is not used when fed through USB.
Notification App
An Android app is available to monitor the current state of the space and notify when it changes. The source code is available on GitHub: Source
The app can be downloaded from Google Play or GitHub
