WE WILL MAKE A CIRCUIT FOR OUR PROTOBOARD SINCE THE COMMON DISPLAY IS VERY SMALL AND TEDIOUS TO CONNECT THEN WE WILL MAKE OUR OWN COMMON CATHODE DISPLAY AND IT IS EASY TO MAKE

Here we will see the schematic diagram made in the easyeda software with all the electronic components and their respective values.

FUNCTIONING

Display 7 Segments Red Common Anode / Cathode - UNIT Electronics

The common cathode display is one whose negative pins (Cathodes) are connected to the same point. This type of display is controlled by 1, that is, the microcontroller or microprocessor assigns each segment a logic 1 or a logic high state.

How does a 7 segment display work? Each of the segments that make up the screen are marked with the first seven letters of the alphabet ('a'-'g'), and are assembled in a way that allows each segment to be activated separately, managing to form any numerical digit.

IN THIS PROJECT WE MADE IT WORK FROM 8V TO 12V SINCE THERE ARE 3 LEDS IN SERIES AND LIMITING THE CURRENT BY A 220ohm RESISTANCE

ELECTRONIC COMPONENTS

  • 21 LEDS 3MM RED
  • 7 RESISTORS 220 OHM 1/4W
  • 1 SPADIN 8 PINS
  • 1 PCB

CHARACTERISTICS

  • VIN 8V -12VDC
  • CATHODE COMUN
  • CONTROL POSITIVE 8V -12V
  • SEGMENT A - G
  • I MAX 150mA
