Electronic Systems

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	First Input Second Input Output 0 0 0 1 1 0 1 1
OR Gate	First Input Second Input Output 0 0 0 1 1 0 1 1
NOT Gate	Input Output 0 1
