The circuit is made out of 8 simple switches connected to a 7-segment LED display called SEVEN_SEG_DECIMAL_COM_A passing through a 150 Ω pack resistor. We used Multisim to create the circuit shown in Figure 3.Multisim software 3.2 Simulation of 7-Segment Display The equipment and material used included: This allows a 4-bit binary number to be used to display all the numbers from 0 to 9.įigure 2 Using a BCD to 7-segment decoder to drive a display 3 EXPERIMENT PROCEDURE AND RESULTS: 3.1 Materials and equipment used Put simply, a BCD 7-segment display decoder is a set of logical structures that takes 4 logic input and output 7 digital signals. How does a BDC to 7-segment display decoder work?Ī BDC to 7-segment display decoder is a combinational logic circuit that takes as inputs four bits of a binary number and produces seven digital outputs to turn on the appropriate segments of the display.The BCD or Binary Coded Decimal (BCD) decoder is a device that converts a digital format of a value into a format that displays devices such as the 7-segment display can interpret into a human-readable For instance, we need to use a BCD to 7-segment decoder in order to display a four-bit binary number from 0000 (0 in base 10) to 1001 (9 in base 10 ) on a 7-segment display In digital electronics, numbers are generally represented by their binary values.What is a BCD decoder and why do we need it to display a number?.As this device is made out of LEDs, it requires resistors order to limit the current supply. The segments are lit on by applying an ‘LOW’ logic level to the cathode. SSD takes generally a 5 V DC power supply and has 7 digital pins named after the first 7 letters of the alphabet (A to G).In order to produce the required number or character, a specific combination of LED segments needs to be illuminated.

Additionally, 7-segment LED to allow the display of letters (A – F) and some alphanumerical 7-segment decoders consist of 7 rectangular LEDs (segments) arranged together in shape of “8”.

A seven-segment display (SSD) is an electronic display device for displaying numbers from (0 – 9).
