Each chapter is project-oriented, combining hardware schematics with low-level C code . Key topics and projects include: Make: AVR Programming: Learning to Write Softwa...

: Learning low-power modes and interrupt-driven I/O for battery-operated devices . Who Is This For? : Implementing UART (serial), SPI, and I2C/TWI

: Direct port manipulation to build "Cylon Eyes" (LED scanners) . : Implementing UART (serial)

The book's primary goal is to teach "bare-metal" or register-level programming . While Arduino provides convenient libraries (like digitalWrite() ), they add overhead. Williams teaches you to:
