I started the assignment by downloading and installing Eagle - which was recently acquired by Autodesk. Eagle is split into two parts, the Schematic and the Board (Routing) windows. In the schematic interface, the placement of each individual component is not so important. What we are looking for in the program is the connection between the components and the micro-controller. Schematic is where you just place all the components that you need into the window. It was quite confusing the reason and order of the components and it is something that I must learn in the coming weeks, the basic of electrical design.
The tricky part in Eagle that I am still understanding is the routing on the Board side of the program. Specifically changes the steps between the snaps - tryign to route the traces of the copper between the components is sort of like solving a puzzle - perhaps I should get better as solving puzzles.
