What happen with the firmware of Snap 4 for Arduino? Standardfirmata?

Huy guys
Please, i need to connect my Arduino One to Snap 4, But Its firmware isnt available. Why?

Welcome to the forum, @lufer2.

StandardFirmata is available to flash from the Arduino IDE itself.

It's under Examples → Firmata → StandardFirmata.

Here's a short guide explaining how to get it installed:
