| Category | (PicoBoards in 2.0), Sensing (in 1.4) |
| Type | Boolean |
| Introduced in | 1.0 |
| Removed in | 3.0 |
The Sensor ()? block was a Sensing block and a boolean block. The block returned whether or not the button on a PicoBoard was being pressed or the specified port was connected.
The block could only be used with a PicoBoard.
It was also the only boolean block that could be displayed as a stage monitor (though before Scratch 2.0, there was also another boolean stage monitor.)
Values
The block had the following options in the drop-down menu:
- button pressed
- A connected
- B connected
- C connected
- D connected
Example Uses
As this block let the project communicate with the outside world, it could be used to operate projects without using the keyboard and mouse; instead, the button could be pressed or the ports connected and disconnected.
Some common uses for the Sensor ()? block were:
- Using a physical button to control a project
- Check if wires are connected properly
