EV3 Ultrasonic Sensor block is not availible in the Home Edition software I can't find the ultrasonic sensor block on the programming app on my computer. I am using the Lego Mindstorms EV3 Home Edition.
You can download the Ultrasonic sensor block (and Gyro sensor too) from the official MINDSTORMS website.
Look for &quot;Ultrasonic Sensor Block&quot; near the bottom of the downloads page.
