Story

Hi! We are currentlt juniors at Sonoma Academy in Santa Rosa. We were tasked with creating a project with at least three different components using a bread board and jump wires. Our creation uses a servo and battery pack to water Kiskas' dying succulent plan. If someone tweets "Water @WilbertThePlant" it receives the code and the red solo cup full of water flips 180 degrees, watering Wilbert! After a red LED flashes to show that the plant has in fact been watered.

Servo servo1;
//This is the servo
int red = D6;
//The light turn red when the servo moves

int servoposition1=0;
// The servo starts at position 0

void setup() 
{
    servo1.attach(A4);
    servo1.write(0);
    Particle.function("waterme",waterMe);
    //When connected to IFTT the function to make the servo move is called waterme
    pinMode(red, OUTPUT);
    //When the servo moves the light turns red
}

int waterMe (String tweet){
    if (tweet == "Water @WilbertThePlant"){
        //To make the servo move and water plant you must tweet "Water @WilbertThePlant"
    servo1.write(180);
    delay(1000);
    servo1.write(0);
    digitalWrite(red,HIGH);
    delay(500);
    digitalWrite(red,LOW);
    delay(500);
    digitalWrite(red,HIGH);
    delay(500);
    digitalWrite(red,LOW);
    return 0;
    //The servo returns to position 0
} else return -1;
