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).
1. Components2. Setup & OperationThere 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).
