Have you ever looked at a map and wanted a quick way to know where a particular business, subway station, or landmark is located? Electronic maps, like the one shown in Figure at Boston's Museum of Science, use lights to mark the positions of local landmarks. Each button on the panel in front of the map corresponds to a location in Eastern Massachusetts. When you press the button for a particular location, its spot on the map lights up.
In this unit, you will make your own electronic map. In Challenge 1, you will construct the map board. In Challenge 2, you will add the electronic components.
Thanks to all.
