Armandas 6, 1 23 Thank you for your interest in this question. I’ve connected a decoder to 7-segment display as shown in figure. Here is a link to a video I made on instagram of mine working using this schematic: Further, this really old chip saved a few transistors by not fully decoding inputs above 0x09, so 0x0A.

Hi guys, could u guys plz tell me which IC is appropriate for 7-segmet decoder to be used in a housing estate company which deals with sustainable building issues? I just want to know the right way to connect the output pins of to the pins of 7-segment display?

Spehro Pefhany k 4 Please kindly give me the circuit diagram of the Digital substitution board with LCD display of two digit on one side or two sided for a football substitution. One of them is the Seven Segment Display. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

This is standard and is shown in the SN datasheet:. Michael George 1, 8 34 Interfacing 7-segment display using decoder.

In the microprocessor binary system, 0Volts will be considered as Binary 0, and 5Volts will be considered as Binary1. Home Questions Tags Users Unanswered. This is standard and is shown in the SN datasheet: Click here to cancel reply. Could please send a circuit for 2 x 7 segment LEDs or two digit display with and ? Look at any other circuit shown for the on the internet and declder will see them all using a resistor on EACH deocder.

The outputs of the are connected to the 7-segment display. Pin configuration of a seven segment display: So, for the number 2 5 segments it will be less than half as bright as the number 1 only 2 segments.

Each segment on a 7-segment display is designated a letter A-G. Because it has attracted low-quality or spam answers that had to be removed, posting an decodeer now requires 10 reputation on this site the association bonus does not count.

Interfacing 7-segment display using 7447 decoder

We are a group of young techies trying to provide the best study material for all Electronic and Computer science students. This circuit is completely incorrect. Then just map the pins correctly again, from datasheet: The pinout is here:. But, in the 1st case, we connect all the 8 pins of the port directly to the LED and control the voltage through the ports manually to display the desired number. However, they don’t seem to mention that you need to have the inputs of the connected to something for it to work like you want it to.
