I have the following script that downloads and processes NOAA satellites. I'd really like some external LEDs to indicate the following;

  1. When the script is running, turn or blink red
  2. When the script is not running, turn or blink green
  3. When the script is within 1 hr of running, turn or blink yellow

I need some assistance in getting a traffic light working WHILE the script is running. I don't know if it's better to call certain other scripts or embed into the existing code (not sure where to do this). I have the LEDs on a breadboard and working fine. Any assistance would be appreciated...thanks.

Got it. Very simple...in BASH

#Defines gpio pin direction
gpio -g mode 17 out #green
gpio -g mode 27 out #yellow
gpio -g mode 22 out #red

#Turns off GREEN led
gpio -g write 17 0


#Turns on RED led
gpio -g write 22 1
