Large size also display the prices are expensive, but they also have a limit if you make yourself big size LED display can achieve. Led diplay pic16f876 used in the control circuit of the LEDs are driven by uln2803 software ccs c prepared by the working frequency of 20MHz.
ULN2803 PIC16F876A BIG 7SEGMENT
PIC16F876A to be used to control all of task on this project.You can replace with any 28 pin PIC microcontroller.PortB set as output to drive all segments.PortC set as output to drive each digit ULN2803 which is octal hight voltage high current darington transistor array The example firmware included in this project is 4digits counter writen for CCS C compiler
