The format is to provide the description of the murder and the clues, then on the next page, provide the solution. Here is a fairly hard sample puzzle, taken from later in this book: Six men whose names are Larry Alberts, Fred Fox, Brian Davis, Jim Martin, John Stevenson, and Marty Graig were in an elevator together. Suddenly, the lights went out. When the lights came back on, Larry Alberts was found stabbed. Other detectives have investigated. They have questioned the suspects, the witnesses, and people who know the suspects. They have collected physical evidence (hair samples, fiber samples, etc.) from the crime scene. They have collected 14 clues, but have not been able to solve the crime. Therefore, they have called in the world's greatest detective, YOU. You must now examine the clues and solve the murder. No two suspects have the same color shoes, hair color, color umbrella, color car, or weight. The suspect who was wearing white shoes has blond hair. John Stevenson was wearing red shoes. Brian Davis has red hair. The suspect who has black hair owns a black car. The suspect who owns a silver car has blond hair. The suspect who owns a blue car was wearing blue shoes. Fred Fox was wearing blue shoes. The suspect who was carrying an orange umbrella is not the one who has no hair. The suspect who was wearing brown shoes is not the one who owns an orange car. The suspect who was wearing white shoes weighs 170 pounds. Jim Martin weighs 220 pounds. Marty Graig was carrying a purple umbrella. The suspect who was wearing tan shoes has black hair. The murderer owns an orange car. There are 7 chapters in this book. Chapter 1 has REALLY easy puzzles just to get you started. Chapter 2 has slightly harder puzzles, and chapters 3 through 5 get progressively harder. Chapter 6 has puzzles of all five difficulty levels, mixed together randomly, so you do not know how hard the puzzles you are solving will be. This can actually be harder than solving a puzzle that you know is considered a hard one, because you do not know how complex your logic must be. In all, there are 75 of these logic puzzles in this book. In chapter 7, I added four cryptograms just to provide you with a change of pace.","brand":"WoB","offers":[{"title":"GB \/ LIKE_NEW \/ INTERNAL","offer_id":49507298410769,"sku":"GOR013509295","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ WELL_READ \/ SBYB","offer_id":50106052509969,"sku":"CIN1517135575A","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":50764204376337,"sku":"CIN1517135575G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":51033596526865,"sku":"NIN9781517135577","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51323352842513,"sku":"CIN1517135575VG","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":53052690137361,"sku":"GOR011640537","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1517135575.jpg?v=1750893034"},{"product_id":"remote-sensor-monitoring-by-radio-with-arduino-book-david-leithauser-9781534640559","title":"Remote Sensor Monitoring by Radio with Arduino","description":"This book is about connecting sensors and radio transceivers to an Arduino so that you can monitor the sensor readings from a distance. You can put the Arduino sensor package miles away from the receiving station, in your front or back yard, or even in your home like your basement or attic. Although the techniques described in this book will work with any type of sensor input, the book will focus on sensors that detect potentially dangerous or disruptive conditions. These will include intruders, fires, flammable gas leaks and other toxic gases like pollution, power failures, floods (including minor floods like a pipe bursting), and other hazards. For the radio communications, we will use the nRF24L01 transceiver chip. This inexpensive chip (usually around $1.00 on EBay) interfaces easily with the Arduino and can both transmit and receive data. It has an advertised range of 100 meters (about 328 feet) for the basic unit, although in actual practice it may be closer to 30 meters (about 98 feet). However, with an optional antenna the range is reported to be 1,000 meters (1 km, about .6 miles). In the first five chapters, I explain the hardware and software aspects of this handy transceiver, enabling you to set up the communications. I even explain how to set up repeater transmitters that can relay the signal from locations beyond the 1 km range. In the chapters after these five chapters, I discuss attaching and operating various analog and digital sensors, explaining how to set them up and integrate them into the transmission software. The chapters will be divided by hazards you can monitor, not specific sensors, so one chapter may include several different types of sensors that can be used to detect the same hazard.\u003cbr\u003e The main sketches in this book an be downloaded from any of these URLs\u003cbr\u003e https: \/\/github.com\/DavidLeithauser\/remote-sensors-Arduino\/tree\/master\u003cbr\u003e http: \/\/LeithauserResearch.com\/RemoteSensors.zip\u003cbr\u003e http: \/\/lrfiles.com\/RemoteSensors.zip\u003cbr\u003e https: \/\/app.box.com\/s\/xsf7e6gsof5jteijvcq7zd38cfwcu53r\u003cbr\u003e See the ReadMe.txt file in the archive for advise on using the files.\u003cbr\u003e All of the sketches in this book have been tested and work as described.
