Here I`ll try to explain what was/is my idea for “home made” trip computer.There is quite many similar ready devices on the market that you can find/buy but unfortunately most of them are developed for OBDII type of cars, what Xantia is not.
Also, you can find few topics over the internet,dedicated on transfer peugeot 406 oem trip computer into Xantia. In my case all began from scratch, based on arduino board.
With little knowledge about arduino board, I found quite interesting topics that people has used Nokia 5110 B&W LCD monitor as screen for some home made devices. And also there are plenty cheap and project-ready ones as module in ebay. And.. i decide to try.
