The Sensor ()? block is a Sensing block and a Boolean block. The block checks if the button on a PicoBoard is being pressed or the specified port connected; if the button is pressed or the port is connected, the block returns true; if it is not, it returns false.
This block can only be used with a PicoBoard.
The block has the following options in the drop-down menu:
- button pressed
- A connected
- B connected
- C connected
- D connected
As this block lets the project communicate with the outside world, it can be used to operate projects without using the keyboard and mouse; instead, the button can be pressed or the ports connected and disconnected.
Some common uses for the Sensor ()? block:
- Using a physical button to control a project
- Check if wires are connected properly
