74HCT04 Hex Inverter IC

The 74HCT04 is a hex inverter IC,
meaning it has 6 inverted (NOT Gates) inside it of which each NOT gate
can perform independently on its own. NOT gates are very useful in
building Logic Combinational Circuits; they can also work independently
as a Wave oscillator or as a Buffer IC.

LM7905 Voltage Regulator

7905 IC is an negative 5V regulator, meaning it
provides -5V as output. The name 7905 signifies two meaning, “79” means
that it is a negative voltage regulator and “05” means that it provides
5V as output. So our 7905 will provide a -5V output voltage.

Transistor Switching Circuit: How Transistor Acts as a Switch

In an NPN transistor, Current starts flowing from collector to emitter only when a minimum voltage of 0.7V is supplied to the base terminal. When there is no voltage on Base terminal it works as an open switch between collector and emitter.

74HC245 8-bit Transceiver IC

The 74HC245 is an 8-bit transceiver IC with 3-state
output. Meaning it has two set of pins (A0-A7 and B0-B7), in which each
set has 8 pins. Out of these two sets one set can be used as input and
the other set can be used as output. Since the IC is a transceiver IC,
Data can flow from input bus to output bus and also from output bus to
input bus, by simply toggling the Direction pin (DIR) pin as required.
It also has a decent output current of 35mA and hence can be used to
drive nominal loads.

Voltage Divider Circuit

A Voltage or Potential Divider Circuit is commonly used circuit in electronics where an input voltage has to be converted to another voltage lower than then the original. This is very useful for all analog circuits where variable voltages are required, hence it is important to understand how this circuit works and how to calculate the values of the resistors required to make a voltage divider circuit to output the desired voltage.

Get Started with Labview

LabVIEW is an acronym of Laboratory Virtual Instrumentation Engineering Workbench. Their appearance and operations resembles real world instruments, such as button, voltmeter, oscilloscope, etc,. and hence they are called as Virtual Instruments (VIs). It offers a graphical programming approach and helps to simulate real world products, which helps you to visualize and program. Thus it requires only logic to program and it is syntax independent. LabVIEW is a high level design tool. It is an interpreter programming (i.e.,) we need not compile it. It compiles itself, we only need to execute it.
