Custom Vibration Patterns

Approach 1: Simple Vibration

The provided demonstrates a React Native app showcasing the usage of the Vibration module. When the user taps on “Start Custom Vibration,” the device produces short-short-short-long-long-long vibrations in a pattern similar to Morse code. Throughout this sequence, the button becomes inactive. Tapping on “Stop Vibration” stops the pattern and reactivates the button.

Example:

Javascript

//App.js
 
import React, { useState } from 'react';
import { View,TouchableOpacity,Text,Vibration,StyleSheet} from 'react-native';
 
const App = () => {
    const [vibrating, setVibrating] = useState(false);
 
    const startCustomVibration = () => {
        setVibrating(true);
        // Short, short, short, long, long, long
        const pattern = [200, 100, 200, 100, 200, 1000];
        // Repeat the pattern
        Vibration.vibrate(pattern, true);
    };
 
    const stopVibration = () => {
        setVibrating(false);
        Vibration.cancel();
    };
 
    return (
        <View style={styles.container}>
            <Text style={styles.heading}>
                w3wiki!
            </Text>
            <TouchableOpacity
                style={[styles.button, vibrating &&
                    styles.disabledButton]}
                onPress={startCustomVibration}
                disabled={vibrating}
            >
                <Text style={styles.buttonText}>
                    Start Custom Vibration
                </Text>
            </TouchableOpacity>
            <TouchableOpacity
                style={[styles.button, !vibrating &&
                    styles.disabledButton]}
                onPress={stopVibration}
                disabled={!vibrating}
            >
                <Text style={styles.buttonText}>
                    Stop Vibration
                </Text>
            </TouchableOpacity>
        </View>
    );
};
 
const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: '#f5f5f5',
    },
    heading: {
        color: 'green',
        fontSize: 30,
        fontWeight: 'bold',
        marginBottom: 20,
    },
    button: {
        backgroundColor: '#3498db',
        paddingVertical: 15,
        paddingHorizontal: 30,
        borderRadius: 5,
        marginVertical: 10,
    },
    disabledButton: {
        backgroundColor: '#bdc3c7',
    },
    buttonText: {
        color: 'white',
        fontSize: 16,
        fontWeight: 'bold',
    },
});
 
export default App;
