Hi all,

does anybody know, if the Color sensor is supported in the current ev3 extension in Scratch 3?
I only see the value for brightness, however nor for color.

Did I miss something?

Eberhard

Hi Eberhard,

Welcome, and thanks for writing! You're right, only the brightness value is reported from the sensor. Generally the LEGO extensions only feature a single mode from a sensor, to keep the extensions simple.

Thanks,
Kevin

I agree that an extension should be simple to use. However, it can be simple while offering the functionality EV3 users expect. Below some things I noticed:

Color sensor:
- At this moment it is impossible to sense colors
- Currently it can only detect “brightness”
- Expected is: Color, Light, Ambient Light, RGB

Motors:
- Motors can currently only spin for a given time duration (one seconds this way or that way)
- Missing is: amount of rotations (not time, but amount of motor rotations) and percentage of power

Is it still not supported?

Scratch doesn't have enough blocks to do more sophisticated programs. If you have a computer it's best to use that to program your EV3 with. Here is a link to a website where you can download the LEGO EV3 Classroom app that uses the drag and drop blocks like Scratch but with way more blocks:
