The revolution in low-cost microcontrollers has enabled DIY enthusiasts to create projects they never could have pulled off before. But the devices can be intimidating and frustrating to use, especially for newcomers. Expensive prototyping and programming systems, difficult programming languages, and hard to decipher data sheets have kept many from using these modern miracles. Until now.

DIY Guru, Thomas Henry has done the research, and brings you this step-by-step guide on programming and building your own useful circuits and projects with the PICAXE 18M2 Microcontroller. Using standard, readily available components, and programming in an easy-to-learn BASIC language, this book presents a comprehensive guide to getting digital power into your next project.

This volume includes:

• 56 projects
• 66 photographs
• 62 schematics
• 56 programs
• 214 pages

Although there are musically oriented projects, this book is a more comprehensive guide for using and programming the PICAXE 18M2. The wide range of projects cover topics like output displays, digital input, analog I/O, DC and stepper motor control, an infrared transmitter, external eeprom, MIDI I/O, and more.
