How to Make Automatic Water Dispenser Machine using Arduino || IoT Project

This is an Arduino project. In this video, you can learn how to make an Automatic Water Dispenser Machine using Arduino.

Components required to make this project are :
1) Arduino UNO
2) Arduino UNO Cable
3) Ultrasonic Sensor
4) Breadboard
5) Relay 5v
6) Jumper Wires ( M To F )
7) Plastic pipe
8) Water pump
9) Cardboard box

}

hello, could you explain your wiring connections on the pump to the COM and NO terminals of the relay?

[DilipKumar-uwly]

As per the video, the below code appears-
//Water dispenser
#define trigger 5
#define echo 4
#define Relay 6
float time=0, distance=0;
void setup()
{
Serial.begin(9600);
pinMode(trigger, OUTPUT);
pinMode(echo, INPUT);
pinMode(Relay, OUTPUT);

delay(2000);
}
void loop()
{
measure_distance();

if(distance<5)
{
digitalWrite(Relay, LOW);
}
else
{
digitalWrite(Relay, HIGH);
}

delay(500);
}
void measure_distance()
{
digitalWrite(trigger, LOW);
delayMicroseconds(2);
digitalWrite(trigger, HIGH);
delayMicroseconds(10);
digitalWrite(trigger, LOW);
delayMicroseconds(2);
time=pulsein(echo, HIGH);

distance=time*200/20000;

}
Any other lines to be added?? Please confirm. Thanks for your help!!
