6.3. Project 2 – LED Dice
6.3.1. Project Description
This is a simple dice project based on LEDs, a push-button switch, and a PIC18F452 microcontroller operating with a 4-MHz resonator. The block diagram of the project is shown in Figure 6.10.

As shown in Figure 6.11, the LEDs are organized so that when they turn ON, they indicate numbers as in real dice. Operation of the project is as follows: normally, the LEDs are all OFF to indicate that the system is ready to generate a new number. Pressing the switch generates a random dice number between 1 and 6 and displays on the LEDs for 3 s. After 3 s, the ...
