Prerequisites

This project assumes you are familiar with the following

• Getting Started Kit - Advanced Lessons - Smart Phidget Events
• pynput with Phidgets

Setup

Make sure you have all the parts before moving on.

Install pynput

In order to use pynput, you first have to install it. You do this in the same way you previously installed the Phidget22 library. Simply navigate to your package manager, search for pynput and press install!

Write code (Python)

Copy the code below into a new Python project. If you need a reminder of how to do this, revisit the Getting Started Course.

  
#Add Phidgets Library
from Phidget22.Devices import *
from Phidget22.Devices.SoundSensor import *
from pynput.mouse import Button, Controller
#Required for sleep statement
import time
 
#Sound Sensor Event
def onSPLChange(self, dB, dBA, dBC, Octaves):
    if (dB > 70): #modify this value based on how loud the sound is
        mouse.press(Button.left)
    else:
        mouse.release(Button.left)
 
#Create
mouse = Controller() #this is from the pynput library
soundSensor = SoundSensor()

#Subscribe to Events
soundSensor.setOnSPLChangeHandler(onSPLChange)

#Open
soundSensor.openWaitForAttachment(1000)

#Set Data Interval to minimum | This will increase the data rate from the sensor to make your program more responsive
soundSensor.setDataInterval(soundSensor.getMinDataInterval())
 
while True:
    # loop forever
    time.sleep(0.1)
  

Run Your Program

Find a game similar to Flappy Bird that uses the mouse as input:

• Example: Helicopter Game.

Run your Python program and move your mouse pointer over the play area. Making a loud noise will start the game. From there continuing to make noise will move the helicopter up, and stopping will cause it to fall.

Practice

1. Try using specific frequencies from the Sound Phidget to move the helicopter.
