هاڻ توهان سمجهي ويا هوندئو ته پروٽو بورڊ يا بريڊ بورڊ اهڙي شي آهي جنهن ۾ پُرزن ڳڍڻ لاِ ڪافي سوراخ هوندا آهن ۽ هُن جي اندرئين تهه ۾ سڌي يا عمودي لائنون به هونديون آهن جيڪي جمپر وانگر پليٽن جيان پاڻ ۾ ڳنڍيل هونديون آهن۔
As you can see from the image below a breadboard has lots of holes, this may seem confusing at first but it really isnt. The 2 rows of holes at either end are for power one for positive (red) one for negative (black).
as you can see i edited the picture below to give you an idea of how circuits are completed.
the power strips go horizontally in 5's where as the component strips go vertically also in 5's.
a circuit is completed when all the desired strips form a loop and are all connected sequentially.
if for instance i wanted to put an led in this circuit by its self i would insert one leg into a free hole of the column where the black (-ve) power jumper is and the other in a free hole of the column that the red wire (+ve) is in. This would complete the circuit allowing current to flow from one side of the power source to the other through the led.
The green lines in the image below form a series circuit where every component touches at different polarities (-ve leg of one component to +ve leg of another) . The forms a single chain of components.
A parallel circuit in this would be that the components you desire to be in parallel would touch at the same polarity (-ve leg to -ve and +ve leg to +ve). so as two colums are needed to accommodate any component with two legs in parallel these components would share the same columns but be in separate holes. if this made no sense dont worry, i will go into more detail later.
