IR_sensor(byte IR_ledPin,byte IR_pdPin);

Description

• Constructor of the sensor
• Parameters are IR_ledPin and IR_pdPin
• IR_ledPin is the pin on which the IR-Led is connected to.
• IR_pdPin is the analog input on which the IR-photodiode is connected to.

Syntax

IR_sensor mySensor(2,A0);

---

~IR_sensor();

Description

• Destructor

Syntax

delete &mySensor;

---

void update();

---

unsigned int value();

Description

• Gets the current value of the IR-photodiode pin.

Syntax

unsigned int value = mySensor.value();

---

Events

You do not know how events work?
Look over here

void onLowTrigger(void (*p_func)());

void onLowTrigger(void (*p_func)(),unsigned int triggerValue);

• Is executed when the IR-light is no longer detected and the signal is above triggerValue.
• NO value accepted.
• NO return values.

void onHighTrigger(void (*p_func)());

void onHighTrigger(void (*p_func)(),unsigned int triggerValue);

• Is executed when the IR-light is detected and the signal is below triggerValue.
• NO value accepted.
• NO return values.

void onBothTrigger(void (*p_func)());

• Is executed when onLowTrigger or onHighTrigger is executed.
• NO value accepted.
• NO return values.
