Here's the code: #define BLYNK_TEMPLATE_ID "" #define BLYNK_TEMPLATE_NAME "Gas leakage alert" #define BLYNK_AUTH_TOKEN "" #define BLYNK_PRINT Serial #include <ESP8266WiFi.h> #include <BlynkSimpleEsp8266.h> char auth[] = BLYNK_AUTH_TOKEN; char ssid[] = ""; // type your wifi name char pass[] = ""; // type your wifi password int smokeA0 = A0; int data = 0; int sensorThres = 100; BlynkTimer timer; void sendSensor(){ int data = analogRead(smokeA0); Blynk.virtualWrite(V0, data); Serial.print("Pin A0: "); Serial.println(data); if(data > 300){ //Blynk.email("test@gmail.com", "Alert", "Gas Leakage Detected!"); Blynk.logEvent("gas_alert","Gas Leakage Detected"); } } void setup(){ pinMode(smokeA0, INPUT); Serial.begin(115200); Blynk.begin(auth, ssid, pass); //dht.begin(); timer.setInterval(2500L, sendSensor); } void loop(){ Blynk.run(); timer.run(); }

Here's the code for the Arduino : #include <Servo.h> #define trigPin 7 #define echoPin 6 #define ledPin 13 Servo servoMotor; void setup() { pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); pinMode(ledPin, OUTPUT); servoMotor.attach(9); } void loop() { for (int angle = 0; angle <= 180; angle++) { servoMotor.write(angle); delay(15); checkDistance(); } for (int angle = 180; angle >= 0; angle--) { servoMotor.write(angle); delay(15); checkDistance(); } } void checkDistance() { long duration, distance; digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); duration = pulseIn(echoPin, HIGH); distance = (duration / 2) / 29.1; if (distance < 10) { digitalWrite(ledPin, HIGH); delay(500); digitalWrite(ledPin, LOW); } }

Here's the code for the Arduino : #include <Servo.h> Servo servoMotor; int servoPin = 9; int initialAngle = 0; int finalAngle = 180; int delayTime = 18000000; unsigned long startTime; void setup() { servoMotor.attach(servoPin); servoMotor.write(initialAngle); startTime = millis(); } void loop() { unsigned long currentTime = millis(); unsigned long elapsedTime = currentTime - startTime; if (elapsedTime >= delayTime) { servoMotor.write(initialAngle); startTime = currentTime; } }

Here's the Code for Arduino --> const int speakerPin = 9; const int ambulanceButtonPin = 2; const int policeButtonPin = 3; const int fireButtonPin = 4; const int ambulanceLowFrequency = 440; const int ambulanceHighFrequency = 800; const int policeLowFrequency = 500; const int policeHighFrequency = 2000; const int fireLowFrequency = 200; const int fireHighFrequency = 3000; const int frequencyChange = 20; void setup() { pinMode(speakerPin, OUTPUT); pinMode(ambulanceButtonPin, INPUT_PULLUP); pinMode(policeButtonPin, INPUT_PULLUP); pinMode(fireButtonPin, INPUT_PULLUP); } void loop() { if (digitalRead(ambulanceButtonPin) == LOW) { playAmbulanceSiren(); } if (digitalRead(policeButtonPin) == LOW) { playPoliceSiren(); } if (digitalRead(fireButtonPin) == LOW) { playFireSiren(); } } void playAmbulanceSiren() { for (int i = 0; i < 5; i++) { tone(9, 440, 500); delay(500); tone(9, 800, 500); delay(500); } noTone(speakerPin); } void playPoliceSiren() { for (int i = 0; i < 10; i++) { for (int frequency = policeLowFrequency; frequency <= policeHighFrequency; frequency += frequencyChange) { tone(speakerPin, frequency); delay(2); } for (int frequency = policeHighFrequency; frequency >= policeLowFrequency; frequency -= frequencyChange) { tone(speakerPin, frequency); delay(2); } } noTone(speakerPin); } void playFireSiren() { for (int i = 0; i < 5; i++) { for (int frequency = fireLowFrequency; frequency <= fireHighFrequency; frequency += frequencyChange) { tone(speakerPin, frequency); delay(8); } for (int frequency = fireHighFrequency; frequency >= fireLowFrequency; frequency -= frequencyChange) { tone(speakerPin, frequency); delay(8); } } noTone(speakerPin); }

Hola me podrías compartir el código por favor

Could I get links to products? Like it's cool, but I think you forget there is alot of stuff online and people get tripped up looking for the right thing

Nice
