ANALOG INPUTS What is the difference between a ‘Digital Input’ and an ‘Analog Input’? A microcontroller is a complete computer system, including a CPU, memory, a clock oscillator, and I/O on a single integrated circuit chip. p. 25 NOTE: Inputs, Outputs (and more specifically, ANALOG and Digital inputs/outputs). What is the difference between Analog and digital? Also, the CRYSTAL and the CLOCK. The crystal creates the ‘beat’, and the clock is the internal signal at the crystal oscillation frequency that synchronizes all operations of the microcontroller. ATmega328 Internal Architecture ATmega328 data sheet pp. 2, 5 The microcontroller is the rectangular-shaped chip, the ATmega328 (dual-inline package, DIP, shown here but surface-mount versions are available and more commonly used for cost reasons). Arduino comprises more than just the microcontroller. Where do you go to get the details on the operation of the microcontroller? The DATA SHEET. (Show the ATmega328 data sheet).
