Breadboard is mainly used to develop temporary electronic circuits for trial and testing purposes. One of its greatest advantage is that it doesn’t require soldering for connecting the electronic components. All you have to do is to just push the leads of the electronic components straight into the holes.
Breadboard has many tiny holes separated by 0.1”. At the top of the breadboard you can find two row’s, each row is horizontally connected with each other, similarly at the bottom of the bread board you can find two row’s, each row is horizontally connected with each other.
In mid portion of a breadboard, you could find two rows separated by a small gap. These holes are connected vertically. Each vertical connection holds five holes which are connected with each others (refer the below breadboard).
And while we connect an IC in a breadboard, we should connect in the manner which is indicated above.
- Always use the horizontally-connected row lines for power supply and for ground connection.
- Connect a small strip of wire between 5th & 6th column in the top and bottom rows (as shown in the above picture).
- Always use black wires for ground and red wires for power supply, so it makes good sense to your circuit design.
- Always keep hookup wires flat on the board.
- Always locate hookup wires around the chip and not over the chip.
- Finally trim the legs of components like resistor, capacitor, transistor and LED’s, so it fixes correctly to the board firmly and by doing this you can avoid the short circuit issues.
