Could you tell me what's wrong with this code? It won't send a message to the user at all.

#include <SoftwareSerial.h> #include <LiquidCrystal.h> SoftwareSerial mySerial(11, 10); LiquidCrystal lcd(7, 6, 5, 4, 3, 2); int gasPin = A0; int buzzerPin = 12; int data = 120; int greenLedPin = 8; int redLedPin = 9; void setup() { Serial.begin(9600); mySerial.begin(9600); mySerial.println("AT+CMGF=1"); delay(1000); mySerial.println("AT+CSCA=\"+639532248926\""); delay(1000); lcd.begin(16, 2); pinMode(gasPin, INPUT); pinMode(buzzerPin, OUTPUT); pinMode(greenLedPin, OUTPUT); pinMode(redLedPin, OUTPUT); lcd.begin(16, 2); lcd.clear(); lcd.setCursor(1, 0); lcd.print("GAS DETECTION"); lcd.setCursor(0, 1); lcd.print("SYSTEM"); delay(1000); lcd.clear(); } void loop() { int gasValue = analogRead(gasPin); Serial.print("Gas Value: "); Serial.println(gasValue); lcd.setCursor(0, 0); lcd.print("Gas Value: "); lcd.setCursor(12, 0); lcd.print(gasValue); delay(1000); if (gasValue > data) { lcd.clear(); lcd.setCursor(0, 0); lcd.print("GAS LEAKAGE");

You didn’t close the last if block and the void loop() function. Add at the end of your code: } } And it might work

looks like an Arduino code. Hard to tell from the partial code. Could be hardware or software problem. Did you upload the program properly? Is your hardware working properly?
