O autorze

Grady Koch emphasizes building things from LEGO that can be applied to practical use in science, engineering, or security.  He is the author of LEGO Optics:  Projects in Optical and Laser Science with LEGO, High-Tech LEGO: Projects in Science, Engineering, and Spycraft with Technic and Mindstorms EV3, and Secrets of Eli’s LEGO Collection.  He also writes for and runs hightechlego.com, which features various LEGO technology projects. His day job since 1987 has been as a research engineer with NASA Langley Research Center. There he works with technology for remote sensing atmospheric phenomena.  He holds a PhD in Electrical Engineering.  And he holds three patents in the field of wind measurements with lidar.

Push into new fields of technology using LEGO and Arduino with the projects in this Cookbook. MINDSTORMS EV3 inventions don’t have to be confined to LEGO factory-made sensors. Incorporate a wide range of sensors, displays, LED arrays, actuators, and even a smartphone into your creations. 

Add amazing capabilities to your LEGOs by building things such as a metal detector, long-range lidar, audio spectrum analyzer, weather station, and a smartphone. Step-by-step instructions bring these new devices to life. You’ll work with the reliable and inexpensive Arduino UNO to take your projects even further and make them truly smart. Learn to set up and program your Arduino UNO. Then learn data communications protocols (I2C, SPI, and PWM) to link sensors to the Arduino. A variety of data communications techniques are also demonstrated on passing data between the Arduino and the MINDSTORMS EV3 Intelligent Brick. 

Equipped with these new tools, LEGO inventors can build vast new capabilities into their designs.

You will:

• Interface new sensors, devices, and communications with LEGO Mindstorms EV3
  
• Work with communication protocols of pulse width modulation (PWM), I2c, and SPI
  
• Convert pulse width modulation to analog voltage with resistor and capacitor components
