Hello, World!

OHM'S LAW 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)

Reading Analog Input

VOLTAGE DIVIDER

A voltage divider splits input voltage input amongst two or more components.

The resisted voltage indicates the value.

Brighter light == Less resistance;

Sending Command & Control Messages

OVERRIDING COMMANDMANAGER 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 (e.g. have I already processes this) Does the CommadManager think this is obsolete?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, andis 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
