Arduino Workshop, 2nd Edition

7 Expanding Your Arduino

In this chapter you will

• Learn about the broad variety of Arduino shields
• Make your own Arduino shield using a ProtoShield
• See how Arduino libraries can expand the available functions
• Use a memory card module to record data that can be analyzed in a spreadsheet
• Build a temperature-logging device
• Learn how to make a stopwatch using micros() and millis()
• Understand Arduino interrupts and their uses

Another way to expand the capabilities of your Arduino is by using shields. A shield is a circuit board that connects via pins to the sockets on the sides of an Arduino. In the first project in this chapter, you’ll learn how to make your own shield. Over time, as you experiment with electronics and Arduino, you can make ...
