Moving the Needles

I've finally succeeded in moving the RPM and Speed dials! It took some months, some burned integrated circuits, a useless H-Bridge and two 2N2222 transistors to get them working.

Here's a video showing a test program.

    I am impressed! I have my own instrument cluster I am trying to get working with an arduino, but I have problems with my speedo pausing at certain positions. Would you be willing to share your code and schematics?

    It could be much easyer if you had an oscyloscope and the car, dont you think?
    I may leave a sugestion: get an oscyloscope and rent the car.... :D

    Hi, good work. I have a Technical question: I have a dashboard without electrical circuit, so I can see 4 gauges (temp,rpm, fuel and speed) with 3 or 4 pin each one. Do you know how can I move the needles? tnx

    Hey, how did you get the air core gauges working with arduino control? I do also have an arduino mega controller, but my use case is real life, I do want control the economy gauge by arduino as boost gauge.
