reset on inactivity (building a morse decoder)

[gerrit1985]

while True:
    key.wait_for_press(timeout) # timeout is seconds as a float, 120 = 2mins
    if not key.is_pressed():
        resetstuff()
    else:
        key_down_time = time.time() #record the time when the key went down
        tone_obj.play(-1) #the -1 means to loop the sound

Thank you very much, i tried it but i get following response:

    tone_obj.play(-1) #the -1 means to loop the sound
    key.wait_for_release()
    key_up_time = time.time() #record the time when the key was released
    key_down_length = key_up_time - key_down_time #get the length of time it was held down for
    tone_obj.stop()
    buffer.append(DASH if key_down_length > 0.20 else DOT)
