FigurE 0-2 A 9-volt battery pack which you can plug into the Arduino to give it power breadboards A breadboard acts as a construction base for electronics prototyping You’ll use a breadboard for all of the projects in this book instead of soldering parts together The name breadboard dates back to when electronics projects were created on wooden boards Hobbyists hammered nails into the wood and wrapped wires around them to connect components without having to solder them permanently Today’s breadboards are made of plastic with predrilled holes called tie points into which you insert components or wires which are held in place by clips under neath The tie points are connected by lengths of conductive material that run beneath the board as shown in Figure 0-3 FigurE 0-3 Breadboard connections THESE PINS ARE CONNECTED HORIZONTALLY THESE PINS ARE CONNECTED VERTICALLY THERE ARE BREAKS IN THE BOARD IN THESE PLACES 5V AND GND ARE ON BOTH SIDES OF THE BREADBOARD Breadboards come in various sizes To build the projects in this book you’ll ideally need three breadboards one full-size typically with 830 holes one half-size with about 420 holes and one mini board with 170 holes The full-size breadboard is ideal for projects 4 Primer
