Firstly I would like to be known that I am complete beginner in Raspberry Pi.
So what I would like to do is monitor my cnc machines status. Every machine has a light tower. Green for machine has finished the process, blinking yellow for machine is working and red for machine has stopped because of an error.
I was thinking if there is a possibility to connect this light tower to raspberry and then a program would send different notification depending which light turned on. FYI light tower uses 12V led.
Is this even possible or even better has anything like that ever been created?
Thank you in advance for all your help.
