About this project

This device is an random number generator using 8x8 LED matrix and driven by Arduino.

It is fully adjustable to work in the range of 1 to 60.

Assembly is very simple and the device can be used in many applications where they require a group of random numbers.

There are two main modes of operation:

Mode 1: Random generation (N = population size and n = sample size).

Mode 2: Timer for draw (1 to 60 seconds).

There are 3 buttons for the setup and operation:

  • Mode: navigation for all modes

(N) population size

(n) sample size

(>) Manual Draw

(>>) Timer of Draw

  • Down: decrease number (for modes N, n or timer).
  • Up: increase number (for modes N, n or timer).
