Electronic systems

Electronic systems can be understood using a systems block approach of input, process and output. This is vital in designing systems to understand how devices are programmed and how they operate.

Input devices allow systems to understand changes in the environment around them. For example, a sensor like a light-dependent resistor (LDR) that senses light levels for street lamps that know when it is dark, or thermistors that detect when it is too hot or cold in a room.
