Flash effect for few buttons (Raspi, GPIOs, LED ...)

[top-specci]

Hi,
now I (we) have time :-(

I just add first LED flash effect for the "COIN" button on my arcade station, so the flash intervall is changing (slow, fast, faster, fast, slow, ...). Normally the LED is simple "ON". Now it's a litte eye catcher ;-)

For this is just connect the LED from one button (COIN) to one of the Raspi GPIO's (LED use only 20mA), and a simple python script run in a endless loop to create the flash effect.

Maybe someone else already have a "nice" python flash effects programmed to control LED(s) from a Arcade-Station, maybe with more than only one LED ?
My idea is to use also the P1 and the P2 button, so at the end I have three LED's to make some interesting "flash effects".
Is there any code I can use and modify if I need/want ?

I will past my simple (and dirty) Python code here also:

import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)

GpioNumber=19
GPIO.setup(GpioNumber, GPIO.OUT)

while True:
   for a in range(1,22):
      GPIO.output(GpioNumber, GPIO.HIGH)
      tms=a*50
      t=((1100-tms)/1000.0)
      time.sleep (t)
      GPIO.output(GpioNumber, GPIO.LOW)
      time.sleep (0.25)

   for a in range (1,25):
      GPIO.output(GpioNumber, GPIO.HIGH)
      time.sleep (0.045)
      GPIO.output(GpioNumber, GPIO.LOW)
      time.sleep (0.025)

   for a in range(1,22):
      GPIO.output(GpioNumber, GPIO.HIGH)
      tms=a*50
      t=((tms)/1000.0)
      time.sleep (t)
      GPIO.output(GpioNumber, GPIO.LOW)
      time.sleep (0.25)

   GPIO.output(GpioNumber, GPIO.HIGH)
   time.sleep (3)
   GPIO.output(GpioNumber, GPIO.LOW)
   time.sleep (0.25)

It's not python code but.. maybe could be useful for you.

While ago - Using gpio and PWM - I did add some flash effects to every buttons on my bartop build.

check out this video

and you can find source code here.

FYI My friend 'sana2dang' made original code for me and I just add little bit.
Although I am not using this any more and moved to RGB effect using Aruino :) but worth trying
