Electronic Systems Flashcards
What is a sensor
The send signals when the conditions around it change
What is a light dependant resistor
When light changes it sends and electrical signal
Light resistance low= electricity flows
Dark resistance high= not so much electricity flows
What is a single flow switch
It controls the circuit by turning it on and off
What is a resistor
Changes the resistance of the circuit, limiting the flow of electricity through a part of the circuit
What is a buzzer
A buzzer makes a noise when receiving and electrical current pass through it
What is a LED, light emitting diode
An led gives out light when receiving an electrical current pass through it
What is a flowchart
A flowchart represents a step by step set of instructions that a programmable component goes through
What does the rectangle represent in a flowchart
An instruction
What does the diamond in a flowchart represent
A question
