This manual is intended for use in an introductory microprocessor or embedded controller course and is appropriate for two and four year electrical engineering technology curriculums. It utilizes the C programming language and the inexpensive, open-source Arduino hardware platform, specifically, the Arduino Uno which uses an Atmel ATmega 328P processor. The manual contains sufficient exercises for a typical 15 week course using a two to three hour practicum period. Some exercises may require more than one period (in particular, the arbitrary waveform generator). The first portion deals strictly with an introduction to the C language using standard desktop tools.
