9.  Side rails create a circuit up and down
 Rows create a circuit (A-E & F-J)

10. Hello, World!

11.  Voltage = current (in amps) x resistance
 V = IR or R = V/I or I = V/R
 Resistance (R) = Voltage (V) / Current (I)
 R = 5V / 15mA (1,000 milliamps = 1 amp)
 R = 5 / .015
 R = 333.333 Ohms (330 Ohms is close enough)
 R = 5V / 10mA
 R = 5/.01
 R = 500 Ohms (560 Ohms is close enough)

12.  5mm Green LED (1)
 330-Ohm 1/4 Watt resistor
(Orange-Orange-Brown) (1)

13. Reading Analog Input

14. A voltage divider splits input
voltage input amongst two or
more components.
The resisted voltage indicates
the value.
Brighter light == Less

15.  Photoresistor (1)
 10k-Ohm 1/4 Watt resistor
(Brown-Black-Orange) (1)

22. Sending Data to the Cloud

23.  Photoresistor (1)
 10k-Ohm 1/4 Watt resistor
(Brown-Black-Orange) (1)
 Update to package.json
 Must rerun npm install
http://ThingLabs.io/arduino/04/

24. Sending Command & Control Messages

25.  isRelevant – should I care about the message?
 Message type is _lightState or _lightLevel and
the message is either from or to this device ID
 isCommand – do I need to execute the message?
 Message type is _lightLevel
 obsoletes – do I care any more? (e.g. have I already processes this)
 Does the CommadManager think this is obsolete?
 Is the downstream message _lightState, and
is it in response to the specified upstream message, and
is the upstream message type _lightLevel
 executeQueue – do whatever needs to be done based on the message
 Iterate the activeCommands and perform some action
 start – get things going
 Starts the CommandManager, gets all the messages and subscribes to future messages

27. Connecting Multiple Things

28.  Permissions enable control over which Principals can interact (or not) with other
Principals
 Permission Types
 admin
 view
 send
 subscribe
 Permissions enable explicit authorization control
 n2 permission add --action subscribe --authorized true
--issueTo <PRINCIPAL ID>
--principalFor <PRINCIPAL ID>
