Coolcircuit presents us a project, based on the PIC16F876A microcontroller. It uses 14 5mm super bright LED’s on each segment. The result is a 6 inch high 7 segment digit display. The circuit can be cascade-connected to form up to an 8-digit display. You can use it as big 7-segment display, big digital clock, digital timer etc.
