Capacitive Touch Sensor Controlled Melody and LED System Using Arduino

In this project, a capacitive touch sensor is used to detect a touch event, which triggers an action on an Arduino Uno. When the user touches the sensor, the sensor sends an interrupt signal through the IRQ pin to the Arduino. The touch event activates the connected components, such as an LED and a buzzer. The buzzer plays two melodies in sequence, and the LED lights up to indicate the touch. The touch sensor works by detecting changes in capacitance when a finger or object comes into contact with the sensor's surface
