                  Our universities are like our mothers. They take our grooming factor to heights. They build up our communication skills. They tell us how to present things in front of others. They make up our body languages and most of all they take our confidence to infinity by removing all hesitations. Our universities especially public sectors provide us international level degree at very low and affordable cost which help us avail great opportunities. They polish our skills and make us able to do something creative and extraordinary. Universities nourish and groom us for years and surely, they have right over any one year of our life as well. We get services and nourishment from our universities and government.                We are quite lucky we because we got such things in our lives but there are millions of children on roads in Pakistan. Those students aren't lucky enough to get care from our society or government. They don't get proper nourishment. They don'

How to use Dot Matrix without Arduino ?

-
Yes, It's true. You can make circuit using Dot Matrix Single color without Arduino. Excited ? Look here it is. 

Let's make this.

Components:

Dot Matrix 8*8 (Single Color. I'm using Yellow)  - 1 Piece 
8 bit DIP switches - 2 Pieces
5 Volt Battery.

IC's

ULN2003A  - 2 Pieces

Transistors

2N3904 Transistor - 8 Pieces 
2SA684 Transistor - 8 Pieces 

Resistors

1K Ohm - 10 Pieces
10 Ohm - 10 Pieces
33 Ohm - 10 Pieces
470 Ohm - 10 Pieces
4.7K Ohm 10 Pieces

TIPS BEFORE GETTING START.

Many people have queries related to Dot Matrix and other things let me clear that.
Single Color Dot Matrix do not have any common anode or cathode. There is just rows and columns, as we are using 8*8 matrix we'll have 8 pins for Columns and 8 pins for Rows and you can connect them in any order.

 Beside this we are using 2 Type of Transistors.

2N3904 

This is NPN Transisitor and here is it's Pin Configuration.

2SA684

This is PNP Transisitor and here is it's Pin Configuration.

Circuit Diagram for DOT MATRIX without using Arduino


I used to 2 breadboards and joined them to make this circuit over it but there was no place left for DIP switches so i didn't used it.

 Here are the pictures.

 I hope this worked for you and you enjoyed the circuit :')

Process Paragraph. How to be in Shape After completing my college life when I entered in professional education, it revealed to me how it was really important to be in shape. We are familiar with a proverb Health is Wealth. We learn we educate ourselves in order to enjoy an adventurous life and to meet our needs. But is it possible to achieve anything without being physically fit? No, It's not possible.One needs to be fit to attain every goal and work hard. My environment and profession demand to be physically as well as mentally fit. So,I decided to start dieting and went to a nutritionist in order to reduce my weight by quitting eating. But she changed my mindset by saying one cannot maintain by quitting eating rather it leads to sickness and weakness. She advised me to make a healthy diet plan and find a way to enjoy exercise. She told me that fit people find a way to actually enjoy their workout. I followed her words and got in a shape within two months. I follo
