Digital Read
Snap! tab location: Sensing tab.
This reporter block will report the latest digital value for the selected pin. Its value is normally "assigned" to a data block for use and read in a loop. A small delay is sometimes added to the loop to lessen the burden on the CPU. .
If a pin has been configured for sonar operation, the latest sonar value is reported using this block.
The data value may also be tested using a conditional block, e.g. If/Then.
(These values are reported for Snap! only - data validation for this block is not possible within Scratch)
