Hi everyone, I am trying to create an odometer, and a trip odometer with EEPROM for a custom car using 7 segment displays, I have background knowledge on how the VSS of a vehicle works, I have the MAX7219 digital display and the TM1637 here, but I've been hunting on Google for guidance on pretty much anything I can work with, and hit quite a few dead ends...I heard that arduino is the place to make these types of circuits. I own an ONU, just been trying out different things, and it's pretty sweet!
I think this topic may have been forumed to death, if it has been, can someone direct me to a link? or if not can someone help me get started with a source code? any help will be great!
Hi there, thank you for the response! I have a 16,000 ppm unit (16 pulse per rotation of the sensor) 3 wire, neg. pos. and send wire (5 volt pulse). I also have another sensor that does 8000 ppm, so I have more to work with. I build dash electronics, RPM, MPH/KM/h gauges, oil pressure, battery, water temp, ect. and I want to add an odometer and a trip odometer to them...I have a schematic for a type of odometer, but it uses old school technology and takes up alot of real estate on the PCB, plus it doesn't retain the info when the power is disconnected...
