Low in price - LOW in content.,
This review is from: Environmental Monitoring with Arduino: Building Simple Devices to Collect Data About the World Around Us (Kindle Edition)
Ok, so this is a cheap book that I bought as an e-book for just a couple of pounds, so why do I feel that it is still of low value?
Well the fact is that it does not live up to the promise of the title or even the sample pre-view. Just too much sizzle and not enough sausage. Much more can be found for free on the web that is better laid out and far better explained.
This book is a valuable lesson in the ...you-get-what-you-pay-for... school of life.
Most of the project 'construction' involves sticking maybe 4 wires from a commercial sensor into a shield then running the code downloaded from GitHub.
The code is reasonably well commented and available free for anyone to download.
The projects promise far more in their titles and descriptions than they deliver in practice. The EMI monitor for example is a 3ft length of wire and a resistor. Noise pollution monitoring turns out to be a microphone stuck in a breadboard. The most sophisticated project is the Geiger counter which basically involves ..er... buying a Geiger counter and hooking up another couple of wires to an 'opto-coupler' using an LDR from Radio shack. The section on using Pachube is basically: read the instructions at Pachube.
Just the title itself offers more than is found in the actual text.
Maybe the authors could add some more content such as: A human interactivity physical bio-feedback monitor-(a switch) or a wide spectrum human auditory canal tester-(a buzzer)or maybe a UFO detector-(requires UFO for calibration)... and then sell the 'upgraded' version for more.
The end of the book has an offer to pay $4.99 to get the same content again in other DRM free formats such as PDF and EPUB which I doubt anyone will ever take up.
