Turn your EAGLE schematic into a PCB

Step 7 Start placing the components

Now we need to move the components to (near) where we want them on the final board. OR we want to move them to sensible places that will make the placement of traces easier. A lot of the "ART" of making PCBs (and especially Single Sided Boards) lies in finding "good" places for the components.

In general, you can start by placing the components similar to how they appear on the schematic. (This breaks down when a chip has multiple gates, or the diagram in the schematic symbol has vastly different pinn placement than the actual chip, but it's a good place to start for discreets and simple components. The worst that will happen is that you'll have a layout that makes sense, even if it doesn't route well...)

In this case, I put the power output transistotrs near lamps that they're associated with, and I looked on the web for a 555 layout that would work well (for the longest time, I tried to do boards with the timing cap placed near the timing resistors, and I always needed a jumper. Sigh.) ("Let no one else's work evade your eyes.")
