Section A: Systems Approach to Designing Flashcards
What is a system
consists of parts/components that work together to control a task/activity
What do system diagrams show
input
process
output
Name 4 input examples
LDR
Pressure sensor
Switch
Temp sensor
Name 2 Process in system diagrams
resistor
microcontroller
What can a microcontroller do
perform tasks of multiple ICs using flowcharts/computer lang
designed to implement spesific function and found in remotes, appliances, toys, some power tools
What are flowcharts
describe the operation of a program in simple terms with symbols
What is an open loop system
represented on a flowchart as doesn’t make decisions/loop back to previous part of charte
What is a closed loop system
contains decision and feedback arrow that leads back to previous stages
Name 4 outputs
buzzer
lamp
LED
Speaker
