Troubleshooting Tips
Sound Sensor Not Detecting Claps
Check sensor wiring, adjust sensitivity (if applicable), and verify pin assignments in code.
LED Not Lighting Up
Confirm LED polarity, resistor value, and correct Arduino pin assignments.
Relay Not Activating
Verify relay connections, ensure sufficient power, and check code for proper triggering.
Erratic Toggling
Adjust clap detection thresholds in code and minimize background noise.
Customization Ideas
+Add Clap Patterns
Program the Arduino to recognize specific clap sequences (e.g., two claps to turn on, three to turn off).
+Use a Relay for AC Lights
Incorporate a relay module to control household AC lights with claps.
+Add Brightness Control
Use PWM to adjust LED brightness based on clap count or duration.
