```c++
#include <Wire.h>
#include <Servo.h>// Initialize servo motor and pump pins
const int servoPin = 2;
const int pumpPin = 3;// Initialize timer module
DS1307 rtc;void setup() {
// Initialize servo motor and pump
pinMode(servoPin, OUTPUT);
pinMode(pumpPin, OUTPUT);// Initialize timer module
Wire.begin();
rtc.begin();// Set timer to dispense sanitizer every 30 seconds
rtc.setInterval(30);
}void loop() {
// Check if timer interval has elapsed
if (rtc.isIntervalElapsed()) {
// Dispense sanitizer
dispenseSanitizer();
rtc.resetInterval();
}
}void dispenseSanitizer() {
// Rotate servo motor to dispense sanitizer
Servo servo;
servo.attach(servoPin);
servo.write(0);
delay(500);
servo.write(180);
delay(500);
servo.detach();// Activate pump to dispense sanitizer
digitalWrite(pumpPin, HIGH);
delay(500);
digitalWrite(pumpPin, LOW);
}
```
### Example 2: Advanced Sanitizer Dispenser with Sensor and TimerThis example demonstrates an advanced implementation of the DIY Sanitizer Dispenser Kit with Timer. The dispenser will dispense sanitizer only when an individual is detected by the IR sensor, and will also keep track of the number of dispenses.
```c++
#include <Wire.h>
#include <Servo.h>// Initialize servo motor, pump, and IR sensor pins
const int servoPin = 2;
const int pumpPin = 3;
const int irSensorPin = 4;// Initialize timer module
DS1307 rtc;// Initialize dispense counter
int dispenseCount = 0;void setup() {
// Initialize servo motor, pump, and IR sensor
pinMode(servoPin, OUTPUT);
pinMode(pumpPin, OUTPUT);
pinMode(irSensorPin, INPUT);// Initialize timer module
Wire.begin();
rtc.begin();// Set timer to dispense sanitizer every 30 seconds
rtc.setInterval(30);
}void loop() {
// Check if timer interval has elapsed
if (rtc.isIntervalElapsed()) {
// Check if individual is detected by IR sensor
if (digitalRead(irSensorPin) == HIGH) {
// Dispense sanitizer
dispenseSanitizer();
dispenseCount++;
Serial.print("Dispense Count: ");
Serial.println(dispenseCount);
}
rtc.resetInterval();
}
}void dispenseSanitizer() {
// Rotate servo motor to dispense sanitizer
Servo servo;
servo.attach(servoPin);
servo.write(0);
delay(500);
servo.write(180);
delay(500);
servo.detach();// Activate pump to dispense sanitizer
digitalWrite(pumpPin, HIGH);
delay(500);
digitalWrite(pumpPin, LOW);
}
```
