Mobile aap konsa hai

I want an app which the sends Mobile notification as a command to hc-05 bluetooth module .please help me anyone

It works but when I try to power it with 9v battery, it malfunctioned, when i enter the password it unlocks it then locks it immediately, why?

this code should work, the code is 23791 #include <Keypad.h> #include <Servo.h> const byte ROWS = 4; // Number of rows in the keypad const byte COLS = 4; // Number of columns in the keypad char keys[ROWS][COLS] = { {'1','2','3','A'}, {'4','5','6','B'}, {'7','8','9','C'}, {'*','0','#','D'} }; byte rowPins[ROWS] = {8, 7, 6, 5}; // Connect to the row pinouts of the keypad byte colPins[COLS] = {12, 11, 10, 9}; // Connect to the column pinouts of the keypad Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS ); Servo servo; int servoPos = 0; // Variable to hold the current position of the servo void setup(){ servo.attach(3); // Attach servo to pin 3 // Additional setup if needed } void loop(){ char key = keypad.getKey(); if (key){ if (key == 'A') { rotateServo(0); // Move servo to initial position } else if (key == 'B') { // Reset code or take necessary action } else { // Check if the entered code is correct if (key == '2') { // Replace '2' with your code's digit if (checkCode()) { rotateServo(89); // Rotate servo if code is correct } } } } } bool checkCode() { // Implement your code checking logic here // For example, compare entered code with stored code // Return true if code is correct, false otherwise return true; // Placeholder, replace with your logic } void rotateServo(int angle) { servo.write(angle); delay(500); // Adjust delay as needed }
