After you have played around with lots of other dashboards and gauges in OBD Car Wizard, you probably want to get started and make your own, right?!

Well making a dashboard is super easy, just follow along with these steps and you should have it done in no time.

Gauges are the building blocks for dashboards and can be used to display any metric, e.g. speed, revs, fuel, etc. The finished gauge we are designing should look like this.

  1. Download the following file to your phone.
  1. Launch OBD Car Wizard and hit the Gauges tab, then the + button at the bottom to Create New Gauge.

  2. Click the Edit icon to start editing the gauge

  3. First of all, enter the basic info for your effect as follows :

  • Gauge Name: Silver Gauge
  • Tags: silver,gauge (anything you like here)
  1. Click on the blue plus icon to add your first layer -> select Add Image -> navigate to the round background you have just downloaded in step 1

  2. You should now have a background for your gauge!

  3. Now time to add some numbers round the side. Click the + icon again -> this time select Add Dial

  4. You now have a number ring which automatically scales to the metric you are using, e.g. 0-8 represents 0-8000 rpm for RPM {pid_revs}, but if you changed the metric to speed {pid_speed}, it would rescale to 0-140 automatically!

  5. Now we need a needle to point to the correct number - download the following file and add this as a new image layer as you did in step 5.

  1. In order to get the correct rotation for the needle, enter the following as your rotation formula: -140 + {tag_pct} * 280

{tag_pct} varies from 0 (min) to 1 (max)

We want to rotate from -140 to +140 so the formula above will rotate accordingly

  1. To add a digital value, click + then Add Text (Expression) -> set the text to {tag_value}

  2. You can move the text to a suitable location, change the text size and color as needed

  3. Your gauge is finished! Hit the back button at the top left of the screen and then you can share with the world when you are ready by using the 'Upload Gauge' action!

  4. That's it! Have fun! And lets see what you come up with!
