WIRE
Wire is responsible for the connection between different circuit boards or executors.
Work with INPUTPIN(input pin) and OUTPUTPIN(output pin).
How to Create a WIRE
First you need to place both INPUTPIN and OUTPUTPIN. Then you can connect those two pins with wire.
The unit at upper-right corner is the OUTPUTPIN.
The unit at lower-left corner is the INPUTPIN.
To create the wire, select WIRE block and click on top of INPUTPIN, then drag the wire to the top of OUTPUTPIN.
Function of WIRE
Signal will flow from OUTPUTPIN to INPUTPIN.
