1) short_range
I show you how to use the ky-037 audio sensor with a monostable multivibrator 74ls123 and a microcontroller rp2040(raspberry pi pico) to build a clap detector that displays the adjustments through a Nokia 5110 lcd(driver pcd8544)
2) long_range
If you need to increase the range, it will be necessary to replace the KY-037 module with an electret microphone with amplification stages. In the project, I have added a schematic made with opamps to achieve this objective.
