I’m making software with Makecode for EV3.

I have a problem that I can’t use 3rd party sensors like Mindsensors-Line Array.

Does anyone know how to use the sensor?

Please teach me about that.

You can take a look at how the built-in sensors are implemented and do something similar. It’s all Typescript. You may need to find out the protocol to talk to that sensor.

So, @nozomihinata, there isn’t really a built-in way to do it. The TypeScript @mmoskal mentioned is [here](https://github.com/microsoft/pxt-ev3/tree/master/libs) BTW

Thanks!

I’m gonna learn about Typescript.
