Electronic systems are made up of:

Input sensors - which detect changes in the environment
Processors - which decide what action is needed
Output devices - which are controlled by the processor and in someway affect the environment

Boolean Logic Gates

Boolean logic gates are binary devices and so inputs and outputs can have values are either 1 for ON / TRUE or 0 for OFF / FALSE.

There are many different types of logic gates, but the 3 most basic are:

AND Gate
