By uploading the Blink sketch to the Arduino, you can check its electrical operation. Unlike the ordinary light bulb, LEDs must be wired properly for them to work. In this chapter, you will learn how to wire two LEDs to the Arduino, as shown in the block diagram in Figure 4-2. The LED projects in this chapter will also use Make:’s MakerShield, but you could use another Arduino-compatible prototyping shield. To add a little creativity to the ...
