• [x] setup time for work & break (defaulted according to Pomodoro technique)
• [x] sound and/or light pattern to show start-up

Cleaned up functions from stubby_eui.py by including parameters to prevent hardcoding pin values. Now, all pin values can be seen in demo.py.

Changed the following functions (the following is not from a file, just a formatted view on github):

workTime() #wDuration parameter set to 25, replaced hardcoded time in work function
breakTime() #bDuration parameter set to 5, replaced hardcoded time in sleep function
setupBtnForTimer() #included timerPin parameter, replaced hardcoded pin
waitForBtnPress() #included timerPin parameter, replaced hardcoded pin
setupSound() #included soundPin parameter, replaced hardcoded pin
makeSound() #included soundPin parameter, replaced hardcoded pin
playMelody() #included soundPin parameter, replaced hardcoded pin
motorTest() #removed GPIO.setmode and GPIO.setwarnings functions bc we have them in demo.py
readDist() #removed GPIO.setmode and GPIO.setwarnings functions bc we have them in demo.py
