Circuit program input

Let us now write the circuit program, starting at the output and working towards the input.

LOGO! initially shows the output:

You will see an underscore below the Q in Q1, which is the cursor. The cursor indicates your

current position in the circuit program. You can move the cursor by pressing the , , and

keys. Now press the key. The cursor moves to the left.

The cursor no longer appears in the form of an underscore; but instead as a flashing solid

square. LOGO! offers you various options here.
Select GF (basic functions) by pressing the key until GF appears, and confirm with OK.
