After the success with CarbonBal using Arduino
https://hackaday.io/project/27569-carbonbal, I knocked up some lights. I have another set using a Pi Zero 2W above the garage door plans for a Pi Pico.
I have to say the Pi Zero is the most user friendly and flexible SBC for little projects like this. It has a desktop, you can debug programs as they run and it's wireless. So it can be told when it should do Christmas lights and when it's just ordinary white lighting.It can also support the Pi security cam. Flashing blue lights might get me into trouble though :-)
Python is more simple for a prehistoric PLC engineer like me as C++ always drives me up the wall.
