An ultrasonic sensor is like the eyes of mBot, which can let mBot know the distance from an object in front. The ultrasonic sensor measures in cm with preciseness to 1cm and maximum measurable distance to 400cm.
Point 2 Why use block
To make the value spoken out by the panda easier to read. Here we use block to show the value. If we do not use the block, you will find the reads on the stage unstable.
