Where

#include "ReactiveArduinoLib.h"

int values[] = { 0, 1, 1, 2, 1, 5, 4 }; 
size_t valuesLength = sizeof(values) / sizeof(values[0]);

auto observableArray = Reactive::FromArray<int>(values, valuesLength);

void setup()
{
	Serial.begin(9600);
	while (!Serial) delay(1);

	observableArray
		>> Reactive::Where<int>([](int x) {return x > 2; })
		>> Reactive::ToSerial<int>();
}

void loop()
{
}

Distinct

#include "ReactiveArduinoLib.h"

auto observableInt = Reactive::FromProperty<int>();

void setup()
{
	Serial.begin(9600);
	while (!Serial) delay(1);

	observableInt
		>> Reactive::Distinct<int>()
		>> Reactive::ToSerial<int>();
}

void loop() 
{
	delay(1000);
	observableInt = 1;
	delay(1000);
	observableInt = 2;
	delay(1000);
	observableInt = 2;

If

#include "ReactiveArduinoLib.h"

		>> Reactive::If<int>([](int x) { return x > 2; },
							 [](int x) {Serial.println(10 * x); })

ForEach

#include "ReactiveArduinoLib.h"

int values[] = { 0, 1, 1, 2, 1, 5, 4 };
