The binary value is the equivalent of the decimal value of 6. Now controlling a 7 datashdet display like this is OK, but we can do much better. Any value above this amount cannot be shown on the 7 segment LED display.
The decimal digit that the 7 segment display shows out depends on the binary value fed into the 4 input data pins DBCA.

We will connect this chip by itself to pushbuttons. This chip saves us a lot of work for that reason. Depending on the combination of pushbuttons being pressed determines the decimal digit that will be shown on the 7 segment LED display; this is summarized in the table above. Each segment is identified by a letter as can be seen below as well as the pinout and schematic for reference.
Driving a 7 segment display with a 4511 BCD to 7 Segment Driver
We can show the digits 0 through 9. This is just for information. With the binary value input, the equivalent decimal value of that binary number is displayed on the 7 segment display.
A BCD to 7 segment decoder circuit is a circuit that intakes a binary value and displays the equivalent decimal value on the 7 segment display. This pin would turn on all the outputs if connected LOW.
Already have an account? These are the pins we attach to each of the corresponding pins on the 7 segment LED display. When HIGH, it is store mode. This provides a little over 5ma for each segment. So we can see which combinations of pushbuttons turned on displays which decimal values.
So the highest value we can feed into iswhich is 9 in decimal. We cannot show any other digits on the 7 segment display.
First we need to familiarize ourselves with the 7 segment module. When HIGH, this feature is not ativated. Otherwise, you would have to know which pins on the 7 segment display to turn on or off, making it much more complicated.
Without the pushbuttons being pressed, the pins are all in a LOW state. Connecting a pin to ground or 0V puts the pin in a LOW state or value. Now we will build a very simple circuit to drive a single digit. Each IC takes a binary number as an input, then outputs the necessary lines to display that number on the 7 segment display. The equivalent decimal value of the binary value we feed into the data input pins will be shown.
Using the pushbuttons, you can manually see how depending on which pushbuttons we press, how the output changes in response.
Using the 7 segments, you can make any decimal digit. The combination of pushbuttons pressed and unpressed determines the decimal digits, according to the binary value. Your shopping bag is empty.
Once you do this the ratasheet will be updated on the 2 LED modules. We are factory specialized in making LED 7-segment display, dot-matrix display, light bar display and abnormity digital display.
You should now see a 4 on the 7 segment LED display. Pin 3 is the LT pin, which is the Lamp Test pin. For example, if we want to display 6 on the 7 segment display, we input the value into the DBCA data pins.
Pin 4 is the Blanking pin. The modules we will be using have a common cathode. The chip is capable of handling up to 20V. There are 4 data pins hold a binary value. The segments are then displayed on the basis of those internal 4511be.
If the pushbuttons dtaasheet pressed, they go to a HIGH state. For example, a on the matches to a on the 7 segment LED display, b matches with b, etc. The decimal equivalent of the binary value that it holds will be displayed on the 7 segment display.
This establishes sufficient power to the chip.
