Summary of LARGE 7-SEGMENT DISPLAY CIRCUIT ULN2803 PIC16F876A

This article describes a DIY large 7-segment LED display project using the PIC16F876A microcontroller. It highlights that custom displays are more cost-effective than commercial ones and details the circuit design where PortB drives segments and PortC controls digits via ULN2803 drivers. The firmware, written in CCS C for a 20MHz frequency, implements a 4-digit counter.

Parts used in the Large 7-Segment Display Circuit:

  • PIC16F876A Microcontroller
  • ULN2803 Darlington Transistor Array
  • Large 7-Segment LEDs
  • CCS C Compiler
  • 20MHz Working Frequency Clock
  • 28-pin PIC Microcontroller (Alternative)
