Building a traffic light control system! 🚦
I'm programming the logic in Ladder via TIA Portal on a Siemens S7-1200 PLC.
Since the PLC outputs are 24V, I used an optocoupler powered by an Elego Uno (Arduino) to safely trigger the 5V LEDs on the breadboard. An industrial push button goes directly to the PLC 24V inputs. 🛠️⚡
