I was curious about how you control Arduino (running Firmata) from OPENRNDR. I searched and all I found was that itwas supported and references to OPENRNDR being successfully used with Arduino. I didn’t find any concrete information _how_ you do it in OPENRNDR.

My guess would be that one would use [firmata4j java library](https://github.com/kurbatov/firmata4j), but I was curious if my assumption was correct.

Hi @torb 🙂

It looks like by adding

```auto
    implementation("com.github.kurbatov", "firmata4j", "2.3.8")

```

to

> <https://github.com/openrndr/openrndr-template/blob/master/build.gradle.kts#L163>

and reloading Gradle the library should be available in your project.

Do you know how to convert the Java code to Kotlin?

What are you going to build? 🙂

Hah, I googled but forgot to check the build file!

I’m not building anything in particular, but I was curious of how working in Arduino (in particular: working with Arduino (and Seeed Grove System) would be compared to Phidgets in a OPENRNDR context.

But I’ll surely post about it in this forum if I ever do something concrete.

Thanks for answering!
