|Category||LEGO Education WeDo 2.0|
The When Distance () () block is a LEGO Education WeDo 2.0 block and a hat block. The block activates when the distance is less than or greater than the specified value, depending on the argument selected from the drop-down menu. Prior to Scratch 2.0, this block did not take a comparison argument but remained with a less-than sign constantly.
This block can only be used with a LEGO WeDo Construction Set.
Some example uses for this block are:
- Activating a motor when the distance sensor is activated
when distance [< v] (10) :: wedo turn [motor v] on for (0.25) seconds :: wedo
- Reporting the distance when it is less than a specified value
when distance [< v] (50) :: wedo repeat until < (distance :: wedo) > (50) > say (distance :: wedo)
