an electronic system is a series of parts or components that control a task or activity
1 of 9
what is a subsystem?
subsystems or subtasks are events or tasks that happen within a system
2 of 9
examples of a subsystem on a car
steering, braking, electrical, power and drive, entertainment, navigation, safety and many more

what is a systems diagram?
separate inputs, processes, decisions and outputs are placed in individual boxes. they are linked with arrows to create a system or subsystem. the arrows show the direction (flow) within the system.
4 of 9
open loop systems
open loop systems do not make decisions based on feedback e.g. a toaster heats bread for a set period of time.
5 of 9
input components
systems and devices are triggered either manually or automatically using switches and sensors, switches are a common form of input. sensors can detect heat, light, movement and sound.
6 of 9
connecting inputs
most input components, especially sensors, work best in a potential divider. the input is connected to both the positive and negative of the power supply through appropriate components. it helps provide a consistent signal to an input pin.
7 of 9
using analogue inputs
analogue components give out varying signals. a potential divider is used to provide the desired voltage in response to changing environmental conditions.
8 of 9
using high-power outputs
some output components require more power than the processing components in the circuit can provide. transducer drivers are used to increase the power available.
