xii PREFACE

All the projects in the book have been • general purpose input-output
programmed using the Mbed integrated de- ports (GPIO)
velopment environment. Broadly, the book • analog-to-digital converters (ADC)
is divided into three parts: basic projects, in- • digital-to-analog converters (DAC)
termediate projects, and advanced projects. • timers
The projects have been organized in the se- • external and internal (timer) interrupts
