Speedometer

Post by lucus » Sat Sep 08, 2018 6:01 am

I made this speedo for my car years ago using a freetronics eleven and the oled display (both from jaycar). It's been in my car for a long time now working fine. I found this forum the other day and thought I'd post it.

I can't remember exactly how I made it but I remember the hardest parts were making a big font that was small enough to fit on the eleven and then finding the speedo wire in the wiring loom and converting it to 5v logic.
