The TRAFFICSIGNAL case

Now enter the command ‘Insert’ ‘Rectangle’, and insert in the same way as the circle a rectangle which encloses the three circles. Once again choose as neutral a color as possible for the rectangle and give the command ‘Extras’ ‘Send to back’ so that the circles are visible again.

If simulation modeis not yet turned on, you can activate it with the command ‘Online’ ‘Simulation’.

If you now start the simulation with the commands ‘Online’ ‘Login’ and ‘Online’ ‘Run’, then you can observe the color change of the first traffic signal.
