The software for this experiment is simple. We create a function that IFTTT passes
through a value. We then check the value to see if it matches and then indicate what sound
we want (such as a buzzer) and turn the motor on. The software for this experiment is as
follows:

#define MOTORPIN A4

#define BUZZPIN D1

void setup() {
pinMode(MOTORPIN, OUTPUT);

pinMode(BUZZPIN, OUTPUT);
Spark.function("Twitter", twitter);
}

void loop() {

}

int twitter(String command)
{
if (command == "buzz")

{
digitalWrite(MOTORPIN, HIGH);
digitalWrite(BUZZPIN, HIGH);
delay(1000);
digitalWrite(MOTORPIN, LOW);

digitalWrite(BUZZPIN, LOW);
return 1;
}

else return -1;
