Excuse me if this a very basic question, but I've just gotten myself a few Arduino's and also two Arduino Stella and I'm trying to understand better how it all works.
I want to attach a led or a little display, or anything really to the Stella, so that I can show the distance to another Stella through a display. I'm not sure if that's possible, or if it is what ports I can use for it.
Would love any guidance, thanks!

I just bought an qwiic to individual cable converter and think (?) that I can use that somehow, right?
Not familiar with that board and I see documentation is very limited. Anyway I don't see why small I2C OLED display couldn't be connected through QWIIC.
Did you try to control the onboard LED?
Thanks! Was able to find out how to access the onboard LED, required some funky nrf_gpio_pin_clear(LED_PIN); to get it to work.
I ordered a cable to connect the qwiic connection and then I should be able to get something to work!
I'm currently trying to figure out why the accelerometer and uwb ranging does not seem to kick in properly when using a 2032 battery compared to the usb port, but making progress so I'm probably just overlooking something!
@kmin I received my Qwiic to individual pin converter cables yesterday and tried to attach it to the rainbow LED thing I have, but it seems quite tricky. From what I can tell the i2c / qwiic format does not really allow you to send digital signals across. Would you have any pointers?
