I am running a python script on a Raspberry Pi, I am using 4 of the gpio pins, 3 as outputs and 1 as an input. When the input is set low it activates a procedure were the outputs are all turned on and off at different times and a sound effect is played using pygame.mixer. I started to have some problems were the input would not activate the procedures anymore. When I looked into it further I discovered that it would only work for 120 times then the input would not activate the procedures anymore and i would get no error message. I am in no way an expert in coding in python so my code is probably messy looking. Here is the code.
