| Tóm tắt: | Before you get overly involved in extending the NXT, you need to understand the history of the
MINDSTORMS concept, and the hardware and software that is available for it. In Chapter 1, we discuss
what comes inside the NXT kit and the RCX sensors that are compatible with it. Let’s void the warranty
by taking them apart and seeing what’s inside. We’ll also provide a brief introduction to NXT-G and NXC,
along with three alternative programming languages. Chapter 3 covers the ins and outs of the NXT and
how to connect to it.
The simplest types of sensors to homebrew are generically referred to as passive sensors. Contact,
resistive, potentiometer, and voltage sensors usually only require a single electronic part, but despite
their apparent simplicity, they can be used to create some interesting projects. Chapters 4, 5, 6, and 7
contain plans for projects such as a surfboard game, an antenna sensor, an Ohmmeter, Temperature
and Humidity Sensors, a theremin musical instrument, a model of Braitenberg’s vehicle, a digital
protractor, two joysticks, and a battery tester.
The 4.3V-powered sensors aren’t a lot more complicated than the passive ones, but you can build even
more interesting projects with them. In Chapter 8, you’ll look at the Hall Effect, infrared rangefinder, and
differential Light Sensors. With them you can build a robot mouse that looks for magnetic cheese, a
vehicle that follows walls, and a digital sundial.
Things get a little more complicated when you look at two-wire powered sensors in Chapter 9. They have
a higher power supply voltage that allows you to use integrated circuit operational amplifiers to measure
very small voltages. The projects include a half volt voltmeter, hot wire anemometer, and calibrated
pressure sensor. Chapter 10 shows you how to add LED control to your homebrew Light Sensor projects |
