if we r connecting all anode pins of 7 segments.. It is called common anode.

Common Anode 7-segment display

  • The Anode, or (+) is supplied, ( pins 3,8 are connected to + through a resistor)
  • So if any of the input pins to turn on the segments go low, they will complete a circuit from (-) to (+) and light a light.
  • For example if there is a low signal (-) on pin 10 the G line in the middle will light up.

if we r connecting all cathode pins of 7 segments.. It is called common cathode.

Common Cathode 7-segment display

  • The Cathode, or (-) is supplied, ( pins 3,8 are connected to - through a resistor. )
  • So if any of the input pins to turn on the segments go high, they will complete a circuit from (+) to (-) and light a light.
  • For example if there is a high signal (+) on pin 10 the G line in the middle will light up.

Why common cathode connection is used in seven segment display using microcontroller 8051?

The output of 8051 micro controller is active high so we must need to use the common cathode type display . it will work glow when any input is high . The anode terminals of leds's of seven segment connected to 8051's output and cathode is common and grounded . so it require common cathode because 8051 provide active high output.


How can you use 7447 to drive a common-cathode display?

When using a common cathode 7-segment display with a 7447 the readout is inverted. Instead of 1000 resulting in an 8, you will see all segments will be off. Since a common cathode display pulls its power from the driving IC chip you could either use an inverter on each input segment or use each 7447 output to forward bias a transistor (turn it on) allowing current draw to come directly from Vcc instead of risking burning out your chip. Note: the series limiting resistors will still be necessary.


What is the difference between a line and a line segment?

Yes there is a large difference between the two. A line has no end and a line segment ends.

What is the difference between a leg and a segment in airline?

I googled and found... Leg/Segment A leg is that portion of the trip between consecutive flight stops. The segment can be a group of legs, because the segment is that portion of a trip from boarding point to a deplaning point.


7 segment display LED?

A seven segment display is a device used to display numbers and letters on things such as alarm clocks. A 7 segment display is simply seven LED's packaged in a pattern that allows numbers and letters to be displayed by illuminating different sets of LED's.
