AVR is the brain that runs Arduino, but you don't need the whole Arduino board to do fun projects. Experimenting with AVR Microcontrollers, from Practical AVR Microcontrollers, shows you how to create a spiffy set of projects that you can build to learn more about electronics, about AVR, and just to generate new ideas for your own projects. Alan Trevennor will show you how to create a secret panel project, a gadget to drive your pets crazy, a hallway lighting system, and even a small home automation network.

In Practical AVR Microcontrollers, you’ll learn how to use the AVR microcontroller to make your own nifty projects and gadgets. You’ll start off with the basics in part one: setting up your development environment and learning how the "naked" AVR differs from the Arduino. Then you’ll gain experience by building a few simple gizmos and learning how everything can be interconnected. In part two, we really get into the goodies: projects! Each project will show you exactly what software and hardware you need, and will provide enough detail that you can adapt it to your own needs and parts availability. Some of the projects you’ll make: An illuminated secret panel A hallway lighting system with a waterfall effect A crazy lightshow Visual effects gizmos like a Moire wheel and shadow puppets In addition, you'll design and implement some home automation projects, including working with wired and wireless setups. Along the way, you'll design a useable home automation protocol and look at a variety of hardware setups. Whether you’re new to electronics, or you just want to see what you can do with an AVR outside of an Arduino, Practical AVR Microcontrollers is the book for you.

This textbook provides practicing scientists and engineers a primer on the Atmel AVR microcontroller. In this second edition we highlight the popular ATmega164 microcontroller and other pin-for-pin controllers in the family with a complement of flash memory up to 128 kbytes. The second edition also adds a chapter on embedded system design fundamentals and provides extended examples on two different autonomous robots. Our approach is to provide the fundamental skills to quickly get up and operating with this internationally popular microcontroller. We cover the main subsystems aboard the ATmega164, providing a short theory section followed by a description of the related microcontroller subsystem with accompanying hardware and software to exercise the subsystem. In all examples, we use the C programming language. We include a detailed chapter describing how to interface the microcontroller to a wide variety of input and output devices and conclude with several system level examples. Table of Contents: Atmel AVR Architecture Overview / Serial Communication Subsystem / Analog-to-Digital Conversion / Interrupt Subsystem / Timing Subsystem / Atmel AVR Operating Parameters and Interfacing / Embedded Systems Design

Atmel's AVR microcontrollers are the chips that power Arduino, and are the go-to chip for many hobbyist and hardware hacking projects. In this book you'll set aside the layers of abstraction provided by the Arduino environment and learn how to program AVR microcontrollers directly. In doing so, you'll get closer to the chip and you'll be able to squeeze more power and features out of it. Each chapter of this book is centered around projects that incorporate that particular microcontroller topic. Each project includes schematics, code, and illustrations of a working project. Program a range of AVR chips Extend and re-use other people’s code and circuits Interface with USB, I2C, and SPI peripheral devices Learn to access the full range of power and speed of the microcontroller Build projects including Cylon Eyes, a Square-Wave Organ, an AM Radio, a Passive Light-Sensor Alarm, Temperature Logger, and more Understand what's happening behind the scenes even when using the Arduino IDE

Do you want a low cost way to learn C programming for microcontrollers? This book shows you how to use Atmel's $19.99 AVR Butterfly board and the FREE WinAVR C compiler to make a very inexpensive system for using C to develop microcontroller projects. Students will find the thorough coverage of C explained in the context of microcontrollers to be an invaluable learning aide. Professionals, even those who already know C, will find many useful tested software and hardware examples that will speed their development work. Test drive the book by going to www.smileymicros.com and downloading the FREE 30 page pdf file: Quick Start Guide for using the WinAVR Compiler with ATMEL's AVR Butterfly which contains the first two chapters of the book and has all you need to get started with the AVR Butterfly and WinAVR. In addition to an in-depth coverage of C, the book has projects for: 7Port I/O reading switches and blinking LEDs 7UART communication with a PC 7Using interrupts, timers, and counters 7Pulse Width Modulation for LED brightness and motor speed control 7Creating a Real Time Clock 7Making music 7ADC: Analog to Digital Conversion 7DAC: Digital to Analog Conversion 7Voltage, light, and temperature measurement 7Making a slow Function Generator and Digital Oscilloscope 7LCD programming 7Writing a Finite State Machine The author (an Electrical Engineer, Official Atmel AVR Consultant, and award winning writer) makes the sometimes-tedious job of learning C easier by often breaking the in-depth technical exposition with humor and anecdotes detailing his personal experience and misadventures.
