Rule 2: Outputs and inputs
● Always create your circuit program by working from the output to the input.
● You can connect an input to several outputs, but not the same output to several inputs.
● Within the same program path you cannot connect an output to an upstream input. You
can use flags or outputs for such internal recursions.
Rule 3: Cursor and cursor movement
The following applies when you edit a circuit program:
● You can move the cursor when it appears as a solid square:
– Press
, , or to move the cursor in the circuit program.
– Press

– Press
or to select a connector or a block.
