Code examples

How to blink a light

blink.ino (spark core)

int led1 = D0;


void setup() {
    pinMode(led1, OUTPUT);
}


void loop() {
    // turn on for 5 minutes
    digitalWrite(led1, HIGH);
    delay(1000 * 60 * 5);
    // delay(1000 * 1);

    // turn off for 55 minutes
    digitalWrite(led1, LOW);
    delay(1000 * 60 * 5);
    // delay(1000 * 1);
}

How to pulse a light

pulse.ino (arduino)

const int LED = 11;

void loop() {
  float in, out;

  for (in = 0; in < 6.283; in = in + 0.001)
  {
    out = sin(in) * 127.5 + 127.5;
    analogWrite(LED,out);
  }
}

pulse.ino (spark)

The Spark Math library does not have sin()!

int led1 = D0;


void setup() {
    pinMode(led1, OUTPUT);
}


void loop() {
    // The Spark Math library does not have a sin()!
    float out;
    for (out = 0; out <= 255; out++) {
        delay(10);
        analogWrite(led1, out);

        if (out == 255) {
            for (out = 255; out > 0; out--) {
                delay(10);
                analogWrite(led1, out);
            }
        }
    }
}

Bean notes

General

• delay() will not evaluate an expression, so don't do math in it to calculate the time to delay in a human readable format.

Development

• Install Bean Loader - https://punchthrough.com/bean/guides/everything-else/downloads/#software-downloads
• Install Ardunio IDE - https://www.arduino.cc/en/Main/Software

As easy as:

1. Write code in Arduino IDE
2. Verify code in Arduino IDE (it's a button to click)
3. Upload code in Arduino IDE (it's another button to click)
4. Program Skitch in Bean Loader (contextual menu item / assumes connection to the Bean is good)
