To create a link first select one of the link buttons in the links toolbar. There are five available link colours to help you organise your breadboard. This puts the current breadboard into links mode and changes the cursor pointer to a cross-hair when your cursor is over the breadboard. When you are in Links mode the only operation available is link creation. To exit Links mode you need to re-select the Free Cursor mode by clicking the Free cursor icon or by pressing ESC which automatically resets to Free cursor mode.
With the Link selected move your cursor to one of the pins you want to link and and click-and-hold your left mouse button down on the pin. There is a small area of snap-to-pin which will move the starting point exactly to the centre of the pin. The link will snap to the nearest pin to the cursor, which means that you don't have the burden of positioning the links precisely. Now with the left mouse button still held down move the mouse cursor (cross-hair) to the pin you want to link to. As you move the cursor a link is pulled from the starting pin to the current cursor position, providing a visual representation of the link being formed.
When the cursor is over the destination pin, release the button. If you got close enough to the second pin a link will be formed between the two pins. (Don't worry - you will know beforehand if the link has been made successfully. The link will dynamically snap to the destination pin closest to the cursor as you move the mouse around). If the link has not snapped to any destination pin at the time you release the mouse button, the link will disappear.
Repeat this process for all the links between PIC PORTB and LED8 Pins and also between the TIMER CK Pin and the PIC RC pin.
The circuit is now ready for a simulation run but before we do we want to tidy up the circuit by aligning the components next to each other.
