This book is where your adventures with Bluetooth LE begin. You'll start your journey by getting familiar with your hardware options: Arduino, BLE modules, computers (including Raspberry Pi!), and mobile phones. From there, you'll write code and wire circuits to connect off-the-shelf sensors, and even go all the way to writing your own Bluetooth Services. Along the way you'll look at lightbulbs, locks, and Apple's iBeacon technology, as well as get an understanding of Bluetooth security-- both how to beat other people's security, and how to make your hardware secure.

Bluetooth devices use radio waves to connect. The radio waves come from a small computer chip. When one Bluetooth device comes close to another Bluetooth device, they send out radio signals to each other. It makes the things we do every day so much more convenient. No wires, cables, or cords, allows you to take computers, game controls, and many other objects from room to room. You can even call your friends from your cell phone while in your car and the sound will come out over the speakers, all thanks to Bluetooth technology! This book will allow students to use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance.

For any readers who have visited Union Square in New York, maybe you have seen a bronze statue standing among the trees of the park. It represents a tall young man, in the close-fitting uniform of an American General of the Revolution. He is erect and with his right hand he clasps a sword against his breast. His left hand is stretched out toward the statue of Washington. His name was Marie Jean Paul Roch Yves Gilbert Motier, better known as Marquis de Lafayette. The story of his whole life is one of the most interesting that has ever been written. This short volume will give only the story of his services to the United States of America, and of his life during the few years in which those services were rendered. The statue was set up in honor of these great services. If you ever embark upon reading the history of the USA, his name will forever be linked with that of General Washington. They were both brave, faithful, just, and generous, and both honored the name of American citizen—a title which Lafayette proudly claimed so long as he lived. =========== KEYWORDS/TAGS: 73, 77, Boy General, action, adventure, admiration, America, André, army, Arnold, attack, Austria, battalion, battle, Boston, brave, British, campaign, Canada, cannon, capture, Carlisle, cause, character, Clinton, command, commander-in-chief, Commissioners, Congress, Cornwallis, Count, countrymen, courage, Deane, Declaration, d'Estaing, Emperor, enemy, England, English, expedition, fight, fleet, France, freedom, French, gallant, garrison, General, government, gratitude, hero, honor, honour, horseback, independence, injustice, Island, Jersey, King, Lafayette, Lee, liberty, Lord, Louis, love, Major-General, march, Marquis de Lafayette, Monmouth, Napoleon, Newport, northward, officers, oppressed, overthrow, Paris, Paul, Philadelphia, Philippe, prison, prisoner, quarters, reconnaissance, reconnoissance, revolution, Revolutionary, River, Rochambeau, services, seventy-seven, seventy-three, soldier, statesman, statue, Sullivan, surrounded, three-cornered, Union, United States, Valley Forge, veteran, victory, Virginia, war, Washington, wound, York, Yorktown, young adult, YA
