Describe:



Arduino projects to save the world show that it requires nothing more than a few tools, some wires and sensors, an Arduino board, and a little bit of glue to build devices that reduce energy bills, help you grow our food, and monitor pollution in the air and the ground, until it warns you of earthquakes. Arduino projects to save the world provide the types of sensors needed to collect environmental data - from temperature sensors to motion sensors. You'll see projects that handle energy sources - from building your own power strip to running an Arduino board on solar panels so you can actually go ahead and build systems that help, for example, lower your energy bills.

 Once you get some data, it's time to use it well by posting it online while collecting it; This book shows you how. The essence of this book deals with Arduino's own projects: calculating heat loss using a heat loss temperature sensor array that sends sensors to every corner of your home for maximum measurement.

 Monitor local seismic activity with your seismograph. Keep Arduino devices alive in the field with a solar powered device that uses an intelligent, energy-efficient design. Monitor your data and devices using a wireless radio; Place your sensors where you want them without worrying about wires. 

Monitor your energy consumption with an advanced monitoring screen that records its data wherever you want. Arduino Projects to Save the World Learn the green systems expert who is ambitious in building environmentally sound Arduino home appliances. Save the Arduino world one at a time.

All about sensors


The main topic of this book is the construction of Arduino science-focused projects. In particular, this The book has a very strong "green focus". What will make these projects possible are the sensors, that is Devices that respond electrically to physical change. Often this response is a change in resistance. For For example, the flexible sensor will change its resistance depending on the amount ofcurvature it is applied to. Basically, The sensor converts an analog (physical) state into another analog (electrical) state, such as The temperature of the resistance or pressure on the voltage.

As such, the microprocessor (who lives in a digital world) cannot understand analog values.
Resistance or voltage means nothing to the microprocessor. We need some way to convert these values To the ones and zeros of the computer language.


Arduino analog to digital converter (ADC)


We will use the ADC analog converter widely throughout the book. Arduino has
ADC is associated with six inputs (called Analog0 - Analog5). A few projects may use all six inputs. we You may want more! The ADC mission is to test the voltage at the specified input pin, Copy this voltage to a byte value, and finally deposit that value into a variable that you specify in RAM.

Basically, ADC does nothing more than make a comparison. Voltage compares
Introduction at analog inputs to another voltage provided at reference input.
