FIGURE 2-8 Too many 555s.

Note that to escape from component adding mode, you need to press the “ESC” key and then click
on “Cancel” in the “Add” window.

Remember that to delete the extra components, you first need to switch to “Delete” mode by
clicking on the “Delete” icon. Until you change modes again, everything you click on will be deleted.
So click on all but one of the NE555 components (Figure 2-9).
