Introduction: Voting System by Using 4-bits Parallel Adder

About: I am a student of BSCS but I'm interested in electronics that's why I would like to think about innovative ideas and try to build my ideas into reality and i also interested in making a robots. email id: degen…

Hello! friends

Welcome to my another voting system by using 4-bits parallel adder project. It's a topic of Digital And Logic Design by Morris Mano (fifth edition) with the help of this project you'll know how voting system works in reality.

So let's get started.

Step 1: Circuit Diagram

With the help of this diagram we can build our own voting system project very easily. Just follow the diagram very carefully. Let me tell you something at the pin 14 of 74ls47 a 330 ohm resistor is attached with 7 segment led's which is not mention in a diagram by mistake.

Step 2: Materials

You'll need

Ic's: (74hc283 x 2), 74ls47 with x3 16 pin bases and Lm7805 (regulator)


Some pieces of jumper wires


Led's: (red x 4), (Green x 6)

7 segment led's x 2 (Anode)

Resistor's: (330 ohms x 12), (1 k x 7)

Switches: spst x 7

Step 3: Component Placing

Place the components according to the diagram on veroboard and soldering it.

Step 4: Soldering and Jumper Wires

This is the back view of voting system project with some solder and jumper wires.

Step 5: Finish

After completing the all steps it's look like this and ready to use. In next step a small video about voting system.

Step 6: Video

Here it's the video watch it carefully and you'll know how it's work.

Thanks for watching.

I hope you guys like it. I'll be back with some new awesome projects.
