As an embedded engineer I would design that as an interlock in the circuit and not rely on firmware

- mschuster91 2y agoAssuming that's possible and the design of the control cabinet isn't boiling down to "a raspi wth a CAN bus adapter" that controls the individual lights via CAN Bus or whatever and an electrical distribution panel for mains AC to the light poles. With old incandescent bulbs you absolutely needed a cabinet full of relays, but given that you can make a fully working traffic light out of Philips Hue lamps, an USB Zigbee controller and a day worth of time, I would not be surprised if a manufacturer opts for going the easy route.
