Clap detection and signalling program for Raspberry Pi
H/w Requirements
- Raspberry Pi
- Microphone [5]
- Audio Card [5]
- Bread Board (optional)
Dependencies
Python 3
- RPi.GPIO
- pyaudio ( PortAudio is needed )
- munch
Other
- Rasbian OS [3]
- Audio Driver [1],[2],[3]
Setting up Raspberry Pi
- Download Raspbian OS
- Install Raspbian OS in RPi
- Configure OS after OS bootup [6]
sudo raspi-config
- Update OS
sudo apt-get update && sudo apt-get upgrade -y
- Install pip & portaudio module
sudo apt-get install -y python3-pip portaudio19-dev
- Connect the output line to BCM #24 Pin on RPi.
( Try 2 claps to activate the output line for 1 sec and 3 claps to toggle ON/OFF state of given PIN. Note: Use 4 claps to exit from the system )
Installing dependencies
# Debian based OS like Ubuntu

Using Pip package
# Using the following command in terminal
pip3 install pi-clap
# Example code for using the package
from piclap.listener import Listener
from piclap.settings import Settings
def main():
config = Settings() # Optional
config.chunk_size = 512 # Reduce as power of 2 if pyaudio overflow
config.interval = 1 # Adjust interval between claps
config.customPin = 13 # Custom config variable
listener = Listener(config) # 'config' argument is optional
listener.start()
if __name__ == '__main__':
main()
