Input Devices: How a System Senses the World

A3.4.1 defined the input stage. This lesson covers the components that actually do the sensing.
Every one of them does the same job: it detects a physical change and converts it into an electrical signal the system can act on.

Analogue or Digital: The First Question to Ask

Analogue Input Devices
1. Produce continuous signals that vary over time.
2. Examples: Temperature sensors, light sensors.
Digital Input Devices
1. Produce discrete signals, often in the form of binary data (0s and 1s).
2. Examples: Switches, digital microphones.
