In the first row: Black boxes are states with switches. They can become true and false. If true, the switch on its right is up and green, if false then its down and red.

You can click on "Set true" or "Set false" to change the direction of the motor that drives the switch.

You can also drag (D) the switches of the black boxes into the upper or lower position, and the switch tends to stay in its current place due to the motor which drives it.

If you need copies of the squares with the black letter in it,
which show the state of the switch, just duplicate these.

In the second row: Operators "OR, AND and XOR". They have two orange-colored input-entries on their top. On the bottom-side is the output named P1 ... upto P9.

In the third row: 8 Operators "NOT". It just needs a single input, and as output it has N1 ... upto N8.

Of cause you can take the output of an operator and use it as input of an other operator! This makes it possible to logically process many combinations of the original states A, B, C,..., H.

This tool doesnt give any task to do, so there must be a seperate worksheet, which explains the specified task.

Further explainations are contained in the text of the rectangle which is left of the operators.
