Interfacing Techniques Flashcards
Is the method of connecting or linking together one device with another allowing us to design or adapt the output and input configurations of two electronic devices so that they can work together.
Interfacing
Convert the voltage and current output of one circuit to the equivalent of another.
Input Interfacing Circuits
Provide an input for information about an environment
Input Sensors
Simplest and most common type of input interfacing device
Push Button Switch
Are mechanical devices that have two or more sets of electrical contacts
Switches and push-buttons
Is used to limit the current in input interfacing
Pull-up Resistor
Its main purpose in input interfacing is to keep the output terminal from floating about by tying it to ground.
Pull-down Resistor
Are individual switches that are grouped together as four or eight switches within a single package.
DIP or Dual-in-line Package Switches
The common problem of mechanical switches
Contact Bounce
Consist of two pieces of metal contacts which are pushed together to complete a circuit when you operate the switch
Mechanical Switches
Multiple switch closing or opening action is called ______ in switches.
Switch Bounce
Produce the same action as switch bounce but for relays.
Contact Bounce
The addition of this circuitry can solve the problem of switch bounce
Debounce Circuit
Simplest debounce circuit that allows the switch to charge and discharge a capacitor
RC Switch Debounce Circuit
This type of switch debounce circuit operates in a very similar way to the SR Flip-flop
Switch Debounce with NAND Gates
