DISPLAY 7 SEGMENTS COMMON CATHODE FOR PROTOBOARD
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
SCHEMATIC DIAGRAM
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
EASYEDA
This project was made in the Easyeda software as we can see the tracks and the 3D image of the project working perfectly are no difficulty
