7 Segment 4 Digit SPI Display Using 74HC595
4 Digit 7-Segment Display Using 74HC595 project drives four 7-Segment Common Cathode display using Serial Shift Register IC. This project provides 4 digits 7-segment display with SPI control for use with microcontroller design.
Applications,
- Timer Display
- Score Display
- Token Display
- Four in number 74HC595 serial shift resistor help you latch the 7-Segment Display with data using LAT, SCLK and SDI/SDO pins available at connectors CN1 and CN2
- Data from the Microcontroller is fed in at CN1 and additional PCBs can be connected in series at CN2 Connector
- The schematic diagram will help you better understand the project and exploit its usefulness in your project
- This project will require 3 I/O lines for control apart from 5 VDC supply pins
- Resistors R1 to R32 helps limit the current flowing through the IC to the display
- Four mounting holes 3.2 mm each
- PCB dimensions 116 mm x 53 mm
