First of all play the simulation and Digits will start to run on Seven Segment Display and at any stage when you will press Button # 1 then Seven segment display will vanish but counting will keep on going in the back. Now the switching of button # 1 includes a very interesting feature.If both the Buttons are kept open and when you will run the simulation then, numerical values will start to come on seven segment display.Left Button in Button # 1 and Right Button is Button # 2. Now if you look closely at the upper portion of the image then, you will notice that i have added 2 buttons in the circuit.then, the resultant simulation will look like as shown in the image below: If you have placed all the components in their exact positions and all the connections are OK. So, the 7 input pin of SSD are connected to the output pins of Shift Register and the common cathode pin is connected to circuit’s main cathode. Since we are using common cathode arrangement. 555 Timer will give clock to the Shift Register.

You can download the complete simulation of above project by simply clicking on the image given below:ĭownload Seven Segment Display Project Using 555 Timer Above was a little introduction of Seven Segment Display and now, lets move towards Hardware and see How this beautiful display is actually formed. In the above image, ‘1’ means ON state and ‘0’ means OFF state of a particular LED of Seven Segment Display. Such table is called TRUTH TABLE and it is shown in the image given below: We can gather this whole information into a single table and also the sequence in which LED’s will blink. We will use a 555 Timer which will continuously provide clock to Shift Register it will enable it’s pin accordingly. In today’s project, we are also going to use the same concept. 555 timer continuously provides clock to the Shift Register and Shift Register gives data to its output pins in parallel manner. Now if you recall one of our previous project tutorial which was Sequential LED Blinking using 555 Timer, In that project, we are using a 555 Timer in collaboration with a Shift Register. A simplest form of Seven Segment Display is shown in the image below:įrom the above shown image, we can see that we have total 7 LEDs and we will make them glow in such a scheme that the final image will look like a Numerical number. In this project we will be using Common Cathode arrangement and Hexagonal shape of Seven Segment Display. In Seven Segment Display all the positive terminals (Anode) or all the negative terminals (Cathode) are brought together to a common pin and such arrangements are known as “Common Anode” or “Common Cathode” arrangement. Seven Segment Displays may uses LIQUID CRYSTAL DISPLAY (LCD) or LIGHT EMITTING DIODE (LED) for each display segment. Seven Segment Displays are commonly designed in Hexagonal shape but according to our project’s requirement we can also design them in some other shapes like rectangle, triangle, trapezoid etc. How they are fabricated and how their LED’s glow in such a beautiful manner? Seven Segment Display (SSD) is the form of electronic device, used to display decimal numbers. So first of all let’s have a little introduction about Seven Segment Display. It is a very simple project to understand Modern Digital Electronics.Īs you all know, now a days all the Digital Display’s uses Seven Segment Display. So today, I am going to share my new project tutorial which is Seven Segment Display using 555 Timer in Proteus ISIS. Yesterday I got a mail from a friend, and he requested me to explain a tutorial about Seven Segment Display. Hello friends, hope you all are fine and enjoying.
