In above picture you can see that we have used both common cathode and anode display to display “A L L”. Now try to make your own alphanumeric display according to the requirement. Therefore we have to connect pin 7, 6, 10, 1, 2 to ground and provide power supply to pin 3 that is DP pin.Īnd you want to make letter “n” than connect pin 1, 10, 4 to ground with the help of resistor and provide power supply to pin 3. Now suppose you want to make numeric “2” than segment which we have to use from figure 1 is “a”, “b”, “g”, “e”, “d”. Always remember to use resistor with individual segment. Common anode display– In this positive pin of all 8 LED’s connected together and negative leads are used as display pin’s. Similarly you can display more alphanumeric on 7 segment display.Ģ. Therefore you have to connect pin 9, 1, 2 to supply and ground pin 3. then segment which you require to glow from figure 1 is “f”, “e”, “d”. Now suppose you want to display alphabet “L”. So connect pin 9, 10, 6 and 4 to supply with the help of 220E resistor and ground DP pin 3 or 8 as both are internally connected to each other. Similarly “g” represent pin 10, “b” represent pin 6 and “c” represent pin 4. Now suppose you want to display numeric “4” than from figure 1, segment which are used to make “4” are as follows “f”, “g”, “b”, “c” and from above “f” represent pin 9. Following figure shows the pin configuration of 7 segment display-įig. As you increase the value of resistor brightness of display decreases. Depending upon the value of resistor your 7 segment will glow more or less. You can use resistor value of 220E to 1K.

Maximum voltage which it can handle is 2.5V and we are powering it with the supply voltage of 5V. In this we have connected every segment with the help of resistor to drop excess of voltage.
7 SEGMENT DISPLAY MULTISIM HOW TO
Following circuit shows how to use 7 segment displays in common cathode mode. So in this configuration negative lead of all LED’s are connected together and remaining leads used as display. Common cathode display – As we know seven segment display are made by combining 8 LED’s. You can also choose colour of your display. Seven segment display comes different size, user can use according to their requirement like 7.6mm, 10mm, 14.2mm etc.Į. Comes with a industry standard pin out which can be directly referred from datasheet.ĭ. It uses low power for its operation less than 2.5V.Ĭ. You can also use more than one display according to your requirement.Ī. Similarly in common anode DP are connected to supply and rest are connected to ground. In common cathode display they are connected to ground and rest pin are connected to supply. 7 segment display are labelled a to g and decimal point is usually known as DP. 7 segment displays numbers from 0 to 9 and some alphabets. But with the basic knowledge of 7 segments display you can use it in front of your shop or you can display your name on it. They have found their use in places like microwave or fancy toaster oven or the same on washing machine but before using them in all these places you need to interface the 7 segment display with microcontroller or some more hardware will be required. IC 4026 is used to drive common cathode 7 segment display.Seven segment displays nowadays are commonly used in place of dot matrix display. There are 10 pins, in which 8 pins are used to refer a,b,c,d,e,f,g and h/dp, the two middle pins are common anode/cathode of all he LEDs. We can refer each line/segment "a,b,c,d,e,f,g" and for dot character we will use "h". It consists 8 LEDs, each LED used to illuminate one segment/line of the unit and the 8thLED used to illuminate DOT in 7 segment display. Reset the counter to 0 when HIGH.Ībove table explains the function of each pin of IC CD4016 clearly. This output is high unless the count is 2, when it goes low. Ungated C-segment - an output for the seven-segment's C input which is not affected by the DE input. The CARRY-OUT (Cout) signal completes one cycle every ten CLOCK INPUT cycles and is used to clock the succeeding decade directly in a multi-decade counting chain Freezes the counter when HIGH, active HIGH.ĭisplay enable- chip will be ON when this pin is HIGH, and OFF if it is LOW. Clock in, Increment the counter with each Positive clock pulse (LOW to HIGH).Ĭlock inhibit - when low, clock pulses increment the seven-segment.
