Anytime the surf sucks in Maui Iâ??ve been working on control systems for the
electrical stuff in the 1978 GMC moho Iâ??m updating. One component is a
wireless brake/turn/tail/backup light using an ESP32. The turn signals are
sequential. Seeing sequential turn signals in a little Lucas taillight would
freak people out. If you werenâ??t going to do all the wacky wireless stuff it
would be easy to combine features with an Arduino and a few MOSFETS, or better
yet a mosfet board that includes opto couplers. The code is pretty simple,
though my current version is written for using MQQT via wirelessâ??for any
geeks out there.
