This is a simple Electric Imp example, which shows how to

interface

the imp with an agent and webpage. This example code goes

handinhand with

an HTML webpage. Check out this page for more informatio

This will show how you can use html color, text, and radi

o form inputs

to control LEDs on/off, PWM them, and set a timer to turn

them off.

Circuit:

A common cathode RGB LED is connected to the imp's pins

1, 2, and 5.

The red anode connects to 1 through a 47 Ohm resistor, gre

en 2, and blue 5.

The cathode of the LED connects to ground.

Another simple, red LED is connected to the imp to imp pi

n 9, through

another 47 Ohm resistor. The cathode of the LED is grounde

imp.configure("LED Web Control", [], []); // Configure the imp

///////////////

// Pin Setup //

///////////////

// Setup reference variables for our pins:

redPin < hardware.pin1; // R of RGB

greenPin < hardware.pin2; // G of RGB

bluePin < hardware.pin5; // B of RGB

ledPin < hardware.pin9; // Lonely red LED

// Configure our pins:

ledPin.configure(DIGITAL_OUT); // Simple digital output

redPin.configure(PWM_OUT, 0.01, 0); // PWM output 10ms cloc

k, off

greenPin.configure(PWM_OUT, 0.01, 0); // PWM output 10ms cloc

k, off

bluePin.configure(PWM_OUT, 0.01, 0); // PWM output 10ms cloc

k, off

/////////////////////////////////

// Agent Function Declarations //

/////////////////////////////////

// setLed will turn the lonely red LED on or off.

// This function will be called by the agent.

function setLed(ledState)

{

ledPin.write(ledState);

}

// setRGB will take a table input, and set the RGB LED accordi
