10. The LEGO Spectrum Analyzer—Arduino Shield with I2C Output to EV3
Yorktown, VA, USA
The sensors used in this book so far have been components that plug into the Arduino board with jumper wire connections. But there are many sensors and controllers that attach onto the Arduino board, called shields, such that they lay up against the Arduino board. Electronic and power connections are made to a shield by the headers on the Arduino board. The use of shields is introduced in this chapter, including incorporation into LEGO projects. The example project is a Spectrum Shield shown in Figure 10-1, made by SparkFun (www.sparkfun.com), that analyzes ...
