The latest iteration of my #PCB to replace the tail lights in my #EV #Mustang arrived earlier from JLC. Looks like 5th times the charm. I managed to actually get this version to do something.

A little bit of coding later and I have a ‘demo’ working.

So, what’s better for nighttime/headlights-on mode? Top and bottom rows permanently on, middle section comes on for brakes? Or middle section permanently on and top and bottom come on for brakes?

Ooh, maybe they should ‘slide’ up and down. There’s 100ms here between rows. Perhaps a little slow.

I don’t love the harshness of LEDs. They go so quickly from off to on. I wanted to try and simulate a bulb a bit by having it ramp up/down quickly. Not sure if it would work. But I screwed up the pin assignment on the MCU (pi pico) in this version. So I think I’ll need to respin this board to get PWM working for all segments.
