Create a Simple Pattern in a 2*2*2 LED Cube
We had seen the arduino program to turn on disgonal LEDs of a 2*2*2 LED cube in previous blog. Here we will create a simple pattern in the 2*2*2 LED cube using arduino.
Circuit is given here. Complete that circuit and upload the following program to your arduino board.
If uploading is successful, a pattern given at the top of this page will be created in your LED cube. By changing the value of "upper_limit", we can adjust the brightness of LEDs. Similarly, by changing the value of "delay_time", we can adjust the speed of illumination.
