What is Breadboard and how its use and connection

What is breadboard?
A breadboard is a solderless device for temporary prototype with electronics and test designs. A breadboard is widely used tool to design and test designs.


A breadboard with holes that allow circuits, wires, and others components to be interconnected without soldering. The breadboard has many holes into which circuit components like ICs, resistors and can be inserted. You can see that how to you insert components in breadboard?


The top and bottom rows of holes are connected horizontally and split in the middle while the remaining holes are connected vertically. A typical breadboard layout consists of two types of region also called strips.  

  • Bus Strip
  • Socket Strip
Bus strips are usually used to provide power Supply to the circuit. It consists of two columns, one for power voltage and other for ground.Socket strips are used to hold most of the components in a circuit. Generally consists of two sections each with 5 rows and 64 columns. Every column is electrically connected from inside.
Note how all holes in the selected row ( rows highlight from pink color ) are connected together, so the holes in the selected column ( columns highlight from blue color ) . The set of connected holes can be called node:
To interconnect the selected row (node A) and column (node B) a cable going from any hole in the row to any hole in the column is needed:
Now the selected column (node B) and row (node A) are interconnected:

Transformerless Led Driver Circuit Diagram

How can make 230 volts LED Driver Circuit without Transformer?
We learn now today that how can use 4 LED'S turns on 230 volt AC without transformer?
In this project, we have design simple 230v LED driver circuit, which can drive LED directly from the main supply.

Circuit Diagram


Required components                                             

1) Resistor 20kΩ/1 watt
2) Polar Capacitor 100uf/16v
3) 4 LED's 8mm (Colors on your Depends)
4) Diode 1N4007

Let we start

You can see this picture how to your require components for his circuit? First of all 4 LED's connected in series after then capacitor (100uf/16volt) parallel of led's and resistor connected with a capacitor of positive terminal and with a negative terminal connected positive side of diode (1N4007) after then this circuit connect with AC supply. You can see this that how connects components in circuit?

Application of 230v LED Driver Circuit Work

This circuit can be used for normal light system.
It can be used as an indicator circuit.
One can fix this circuit with the door bell to given indication.

Advantages


With the help of this 230v LED Driver circuit, we can drive LED's directly from the main supply.
This project is based on a transformer less supply. Hence the final build won't be a large one.
