Follow the diagram closely and double check all connections before powering up the circuit.

Configure the Threshold Potentiometer

The potentiometer in the circuit allows you to adjust the sound threshold. This sets the volume level at which clapping will activate the LEDs.

To configure:

Some experimentation may be needed to find the ideal setting.

Optionally Add a Reset Switch

An optional enhancement is adding a reset switch to clear the LEDs after they have been triggered. This gives you manual control to reset the light show.

To add a reset switch:

Troubleshoot Issues

If the circuit is not working, here are some troubleshooting tips:

Carefully going through the circuit step-by-step helps identify any wiring errors or defective components.

Optional Enhancements

Once you have the basic clap-activated circuit working, there are several enhancements you can add:

The possibilities are endless! The simple clap-sensing circuit can serve as the foundation for many creative projects.

Conclusion

Constructing a DIY sound-activated LED circuit that responds to claps is a rewarding electronics project that puts your prototyping skills to use. Following this guide, you learned how to:
